More Details on Our Top Picks
Outsidepride Indian Summer Gloriosa Daisy Seeds – 400 Pcs Perennial, Heat & Drought Tolerant Rudbeckia Hirta Flower Seeds
This seed mix stands out for its vibrant, daisy-like flowers that bloom reliably from early summer through fall, making it an excellent choice for gardeners seeking bold color in hot, dry conditions. Compared with Gaillardia Mesa Peach, which offers stunning bi-color blooms, the Indian Summer Gloriosa Daisy provides a more extended bloom period and self-seeding ease, though it may require patience for seed establishment. Its tolerance for drought and heat across USDA zones 3–10 makes it a versatile addition to many landscapes. However, it demands full sun to achieve its best flowering, and in colder zones outside USDA 3, additional protection could be necessary. This pick is ideal for those wanting low-maintenance, pollinator-friendly perennials that thrive with minimal watering.
Pros:- Vibrant, large yellow flowers that brighten garden beds
- Pollinator-attracting and beneficial for local ecosystems
- Resilient and drought-tolerant across multiple zones
- Low-maintenance, self-seeding perennial
Cons:- Requires full sun for optimal flowering
- Seeds may take time to establish and bloom
Best for: Gardeners seeking a colorful, drought-tolerant perennial with easy self-seeding habits for sunny borders or meadows.
Not ideal for: Gardeners in cooler climates outside USDA zone 3 who prefer quick blooms or less establishment time.
- Expected Blooming Period:Summer to Winter
- Sunlight Exposure:Full Sun
- USDA Hardiness Zone:3
- Expected Plant Height:2 Feet
- Soil Type:Loam
- Soil Moisture Needs:Little To No Watering
Our verdict“This perennial excels in hot, dry settings, making it perfect for low-water gardens needing long-lasting color.”
Spring Charm Arabis 500 Mg ~530 Seeds – Arabis blepharophylla – Second-Year Blooming Perennial with Fuchsia & Lavender Flowers
This perennial ground cover stands out for its fragrant, fuchsia and lavender blooms that attract butterflies and hummingbirds, offering a delicate yet resilient addition to sunny or partially shaded dry landscapes. Unlike the more showy but less adaptable Gazania mix, Spring Charm Arabis provides a lush foliage base with charming flowers appearing in its second year, rewarding patience. It thrives in poor, well-drained soils and tolerates heat and drought, making it ideal for rock gardens, slopes, or borders where other plants struggle. The need for starting indoors 6-8 weeks before planting may be a hurdle for some, and blooming in the second year means immediate impact isn’t possible. This choice is best for gardeners willing to wait for a fragrant, pollinator-friendly ground cover that performs well in dry conditions.
Pros:- Attractive, fragrant flowers that draw pollinators
- Drought and heat tolerant, suitable for dry sites
- Non-GMO, heirloom seeds for sustainability
- Perennial with second-year bloom potential
Cons:- Requires indoor starting 6-8 weeks before planting
- Blooming occurs only in the second year, delaying visual impact
Best for: Landscapers seeking a fragrant, drought-tolerant ground cover to fill sunny, rocky spaces with color and scent.
Not ideal for: Beginners looking for quick-blooming perennials or those who prefer perennials that flower in the first year.
- Plant Type:Perennial ground cover
- Blooming Age:Second year
- Flower Colors:Fuchsia and lavender
- Seeds per Ounce:Approximately 60,000
- Pollination:Open-pollinated
- Tolerance:Drought and heat tolerant
Our verdict“This resilient ground cover is well-suited for dry, sunny areas where fragrance and pollinator attraction are priorities.”
300 Perennial Mix Gazania Seeds – Drought Tolerant Ground Cover and Wildflowers for Gardens
This seed mix offers vibrant, large blooms in a variety of colors, making it an excellent choice for ground cover, containers, or hanging baskets. Compared with the Gaillardia Mesa Peach, which blooms later and has a more specific color palette, Gazania provides an immediate splash of color from early summer through frost. Its ease of growth and drought tolerance make it accessible even for novice gardeners, though it is considered an annual in northern regions and may be short-lived if not reseeded. Its preference for full sun ensures maximum vibrancy, but in cooler climates, it may not last beyond a season. This mix is perfect for gardeners seeking quick, colorful coverage with minimal fuss.
Pros:- Vibrant, large blooms with a long blooming season
- Easy to grow and drought-tolerant
- Versatile for ground cover, containers, and baskets
- Reseeds naturally for continuous color
Cons:- Considered an annual in northern regions
- Short-lived in some cases, requiring reseeding
Best for: Home gardeners wanting fast, colorful ground cover or container plants that withstand drought and heat.
Not ideal for: Those in colder or northern climates expecting long-lived perennials, as it may be short-lived or an annual there.
- Seeding Rate:2-3 seeds per plant
- Plant Height:8-10 inches
- Bloom Colors:Yellow, orange, red, pink, white, striped
- Growth Habit:Annual in North, short-lived perennial in South
Our verdict“This colorful, easy-care mix offers quick coverage and bold blooms ideal for warm, sunny spots needing a splash of color.”
Gaillardia Mesa Peach Seeds, Drought-Tolerant Perennial Blanket Flower, 25 Seeds
This pick shines for its vibrant bi-color flowers in yellow and orange with a striking red center, blooming from late spring through fall. Compared to the Gazania mix, which offers a broader spectrum of colors and quick blooms, Gaillardia Mesa Peach provides reliable, long-lasting color in hot, dry environments, attracting a variety of pollinators. Its compact height of 10-12 inches makes it suitable for borders, rock gardens, or containers. The plant’s high drought tolerance and minimal care needs make it ideal for gardeners in arid climates or those seeking low-maintenance perennials. However, it prefers full sun and may not perform well in humid or cooler regions. This perennial is best for those prioritizing extended bloom periods and pollinator support with minimal watering.
Pros:- Vibrant, bi-color flowers from late spring to fall
- Drought-tolerant and low-maintenance
- Attracts pollinators like butterflies and bees
- Compact size suitable for various garden settings
Cons:- Requires full sun for best performance
- Limited to regions with hot, dry conditions
Best for: Gardeners in hot, dry climates seeking a colorful, long-lasting perennial that attracts pollinators.
Not ideal for: Gardeners in humid or cooler climates expecting rapid growth or larger mature plants.
- Quantity:25 seeds
- Plant Height:10-12 inches
- Bloom Color:Yellow, Orange, Red
- Sunlight:Full Sun
- Soil:Well-drained
Our verdict“This drought-tolerant blanket flower delivers dependable, colorful blooms throughout the growing season in arid gardens.”
Outsidepride Sweet William Dianthus Seeds – 5000 Pcs, Perennial Wildflower for Pollinator Gardens
This extensive seed pack produces fragrant, colorful blooms that last from late spring into early summer, offering a classic wildflower look with strong pollinator appeal. Unlike the more specialized or heat-tolerant options, Sweet William is better suited to cooler USDA zones 3–9, where it can thrive with minimal care. While it provides reliable vertical interest, its bloom period is relatively limited, mainly concentrated in late spring and early summer, unlike the continuous flowering of Gazania or Gaillardia. Its low water needs and adaptability to various soils make it suitable for low-maintenance gardens, but growers in extreme heat zones may find it less durable or require extra care. This seed is ideal for gardeners in temperate climates wanting a fragrant, pollinator-friendly perennial with lasting beauty.
Pros:- Vibrant, fragrant flowers in multiple colors
- Hardy perennial suitable for various climates
- Low-maintenance and drought-tolerant
- Attracts bees and butterflies
Cons:- Bloom period limited to late spring and early summer
- Requires 8-12 inches spacing for best growth
- May need protection in extreme cold zones
Best for: Gardeners in USDA zones 3–9 seeking a fragrant, colorful perennial that offers long-lasting blooms with minimal watering.
Not ideal for: Hot, drought-prone gardens in USDA zones outside 3–9 or gardeners desiring year-round bloom.
- Quantity:5000 pieces
- Expected Plant Height:2 feet
- Blooming Period:Summer to Fall
- USDA Hardiness Zone:3-9
- Soil Type:Loam
- Soil Moisture Needs:Little to no watering
Our verdict“This perennial wildflower offers reliable, fragrant blooms in temperate climates with minimal fuss, perfect for pollinator gardens.”
CarpetC 200+ Mixed Gazania Seeds for Planting, Perennial Ground Cover Gazania rigens, Heat & Drought Tolerant, Non-GMO Heirloom for Gardens, Borders & Containers
This seed collection stands out for its vibrant, daisy-like flowers in a variety of colors that thrive in hot, dry conditions, making it ideal for xeriscaping and coastal gardens. Unlike the single-color options, this mix offers diversity that can brighten any landscape. A key advantage is its low maintenance: it requires minimal watering once established and blooms from late spring through fall, providing long-lasting color. However, it demands full sun for best performance and may not bloom in shaded or cloudy areas. Compared to the more uniform appearance of the Delosperma ‘Fire Spinner,’ this seed mix offers more color variety but may require more attentive watering and care in cooler zones, where it must be grown as an annual or overwintered indoors. Overwatering can cause root rot, so proper drainage is essential. Overall, this option makes the most sense for gardeners seeking colorful ground cover that can handle high heat and drought with minimal fuss.
Pros:- Highly heat and drought tolerant, perfect for xeriscaping
- Vibrant, long-lasting daisy-like flowers in multiple colors
- Low maintenance and easy to grow from seed
Cons:- Requires full sun for optimal blooming
- May not perform well in shaded or cloudy conditions
- In colder zones, must be grown as an annual or overwintered indoors
Best for: Gardeners in USDA zones 8-10 seeking colorful, low-maintenance ground cover that tolerates drought and coastal conditions
Not ideal for: Gardeners in cooler zones or those seeking perennial plants that bloom in partial shade or with less direct sun
- Plant Type:Perennial ground cover
- Flower Colors:Mixed (orange, yellow, pink, red, white)
- Growth Height:6-12 inches
- Blooming Season:Late spring through fall
- Germination Time:10-28 days
- Zones:8-10 (perennial), others as annual
Our verdict“This seed mix excels for gardeners wanting a colorful, resilient ground cover that thrives in full sun and dry conditions, especially in warmer zones.”
300 Gazania Seeds Mix – Heat & Drought Tolerant Garden Flowers & Ground Cover Plants
This Gazania seed mix is designed for gardeners wanting large, eye-catching blooms that last from early summer until frost, making it a strong choice for border edging and containers. Unlike the mixed seed collection, this option emphasizes bigger flowers and continuous color, attracting pollinators and reseeding prolifically. It tolerates a range of soils and drought, but is considered an annual in northern climates, which limits its perennial appeal there. Compared with the CarpetC mix, this product offers larger blooms but shorter overall lifespan in cooler zones. It requires full sun and moderate watering for optimal results. Its reseeding ability means it can naturally replenish each year, but this can also lead to unwanted spread in some gardens. For those seeking vibrant, large-flowered plants that perform well in full sun, this seed mix offers a dependable choice, though it won’t provide lasting perennial stability everywhere.
Pros:- Vibrant, large blooms with long-lasting color
- Drought tolerant and adaptable to various soils
- Attracts pollinators and reseeds easily
Cons:- Considered an annual in northern climates
- Short-lived perennial in some regions
- Requires full sun for best growth
Best for: Gardeners in USDA zones 9-11 who want large, long-lasting summer blooms in beds or containers
Not ideal for: Gardeners in cooler regions seeking true perennials or plants that reliably reseed without volunteer spread
- Expected Plant Height:0.1 Inches
- Moisture Needs:Moderate Watering
- Number of Pieces:300
- Seeding Rate:2 – 3 seeds per plant
- Materials & Care:GMO Free
- Usage:Indoor, Outdoor
- Sunlight Exposure:Full Sun
Our verdict“This seed mix is perfect for gardeners wanting big, colorful flowers that bloom all summer in warm, sunny spots, with reseeding providing ongoing display.”
Perennial Farm Delosperma ‘Fire Spinner’ – Live Groundcover in 1 Quart
This Delosperma ‘Fire Spinner’ shines as a vivid, succulent groundcover that offers a splash of fiery orange and pink from late spring through summer. Compared to seed-based options like the Gazania mixes, this live plant provides instant impact and dense coverage, especially suited for rock gardens, edging, or sunny slopes. Its drought and heat tolerance are top-notch, making it ideal for xeriscaping. The plant’s dense, low-growing habit requires spacing of around 18 inches for full coverage, and it may go dormant or be trimmed back if shipped during winter. It’s best suited for gardeners seeking an easy-care, colorful addition to hot, sunny landscapes, though it demands full sun and well-drained soil to thrive. Unlike the seed options, it involves a higher initial cost but offers immediate visual impact and reliable performance.
Pros:- Vivid orange and pink flowers add striking color
- Drought and heat tolerant, suitable for xeriscaping
- Low maintenance and deer resistant
Cons:- May be dormant or trimmed if shipped during winter
- Requires full sun for best growth
- Spacing of 18 inches needed for full coverage
Best for: Gardeners wanting instant color with low-maintenance, drought-tolerant groundcover in zones 5-10
Not ideal for: Gardeners seeking fast-growing plants for shaded or moist areas, or those on a tight budget
- USDA Hardiness Zone:5-10
- Expected Blooming Period:Spring to Fall
- Expected Plant Height:24 Inches
- Soil Type:Loam
- Soil Moisture Needs:Moderate Watering
- Color:Fire Spinner
Our verdict“This live groundcover is excellent for those seeking immediate visual impact and reliable drought tolerance in sunny, well-drained locations.”
HOME GROWN Verbena Moss Seeds – 6000+ Perennial Flower Seeds for Ground Cover, Erosion Control, and Pollinator Attraction
This seed packet packs over 6,000 non-GMO Verbena Moss seeds, making it ideal for creating a lush, long-blooming ground cover that attracts pollinators. It excels in naturalized areas, erosion-prone slopes, or large beds needing ecological benefits. Compared with the more ornamental Gazania options, this plant emphasizes ecological value and extensive coverage. Its drought-resistant, low-maintenance nature suits gardeners aiming for a naturalized look or erosion control. However, it requires some initial care—pinching or deadheading can help it reach full density. In frost-free zones, it behaves as a perennial, but in colder climates, it acts as an annual, limiting its year-round appeal. Overall, this seed is perfect for eco-conscious gardeners seeking a resilient, pollinator-friendly ground cover with extensive seed quantity.
Pros:- Over 6,000 seeds for extensive coverage
- Attracts pollinators like bees and butterflies
- Low maintenance and drought resistant
Cons:- Requires some initial care for best results
- May need pinching or deadheading to promote density
- Perennial only in frost-free zones, otherwise annual
Best for: Gardeners in frost-free zones seeking large-scale, pollinator-attracting ground cover and erosion control
Not ideal for: Gardening newcomers or those wanting immediate plant impact, as it requires initial care and patience
- Quantity:6000+ seeds
- Type:Perennial flower seeds
- Planting zones:Frost-free zones, annual in extreme climates
- Features:Heat-tolerant, drought-resistant, low maintenance
Our verdict“This seed mix offers a cost-effective way to establish a resilient, pollinator-friendly ground cover across large areas, especially in naturalized settings.”
Perennial Farm Echinacea (Coneflower) – Live Perennial with Vibrant Daisy-Like Blooms
This Echinacea variety provides sturdy, long-lasting blooms that are highly attractive to butterflies and hummingbirds, making it a favorite for pollinator gardens. Its vibrant, deep rose-purple petals and cone create a striking focal point. Compared to the seed-based Gazania or Delosperma options, this live perennial offers immediate impact and reliable performance in USDA zones 3-9, withstanding drought once established. Its sturdy stems require no staking, and it blooms from mid to late summer through fall. However, it is unsuitable for zones outside 3-9 or for gardeners seeking plants that bloom in early spring. It may be dormant or trimmed if shipped during winter, which could affect appearance initially. This choice best suits those prioritizing long-term perennial stability with high ecological value.
Pros:- Vibrant, long-lasting flowers attract pollinators
- Sturdy stems that do not require staking
- Drought tolerant and full sun compatible
Cons:- Limited to zones 3-9
- May be dormant or trimmed if shipped during winter
- Less immediate impact compared to live plants
Best for: Gardeners in zones 3-9 seeking resilient, long-blooming flowers that attract pollinators and require minimal staking
Not ideal for: Gardeners in colder or warmer zones outside 3-9, or those wanting quick, immediate flowering from seed
- Plant Type:Perennial
- Bloom Size:3-4 inches
- Height:20-24 inches
- Color:Deep rose-purple petals with rose-tinted dark orange cone
- USDA Zones:3-9
- Sun Exposure:Full sun
Our verdict“This Echinacea is an excellent choice for gardeners wanting dependable, long-blooming pollinator flowers in suitable zones, emphasizing ecological benefits.”
Purple Showers Ruellia Live Plants – Pack of 2, 5-9 inches tall, Tall Mexican Petunia, Heat Tolerant Perennial for Rain Gardens & Borders
Compared with the Lantana seeds, Purple Showers Ruellia offers an immediate visual impact with its tall, violet blooms that last from spring to frost. Its adaptability to both wet and dry conditions makes it ideal for rain gardens and xeriscapes, especially in zones 8-11. The sterile cultivar ensures no unwanted reseeding, but its tall growth habit means some support might be necessary for stability. Unlike Lantana, which requires a longer time to establish from seed, these starter plants provide instant height and color. However, in colder zones, it behaves more like an annual, requiring replanting each year. The plant’s resilience to deer and pollinators makes it a dependable choice for low-maintenance, high-impact gardens.
Pros:- Vivid violet blooms that last from spring to frost
- Highly adaptable to wet and dry soil conditions
- Sterile cultivar prevents unwanted reseeding
- Deer-resistant and pollinator-friendly
Cons:- Requires staking or support due to tall growth
- Behaves as an annual in colder zones, needing replanting
Best for: Gardeners seeking an immediate, tall, and colorful perennial that withstands wet and dry extremes in moderate to warm zones.
Not ideal for: Beginners expecting quick growth from seed or those in colder zones where it won’t reliably overwinter without extra protection.
- Quantity:2 plants
- Height:5-9 inches (starter plants), 3-4 feet mature height
- Zones:8-11 (perennial), 4-7 (annual in colder zones)
- Color:Deep violet
- Plant type:Perennial / Annual (depending on zone)
- Growth habit:Upright, tall
- Sun exposure:Full sun to partial shade
- Soil:Any soil type
Our verdict“This pick makes the most sense for gardeners in zones 8-11 wanting instant color and tall, resilient plants for borders or rain gardens.”
300+ Lantana Flower Seeds – Colorful Perennial Mix, Attracts Butterflies & Hummingbirds, Drought & Heat Tolerant, Long-Blooming Garden Flowers
While Purple Showers Ruellia provides an immediate, tall, and vibrant perennial, the Lantana seeds offer a flexible and cost-effective way to fill garden beds with colorful, long-lasting blooms that attract pollinators. Lantana’s drought and heat tolerance make it a natural choice for dry climates, and its ability to bloom from spring through fall surpasses many perennials in continuous color. Compared to Ruellia, which requires some initial support and zone considerations, Lantana can be grown easily from seed with patience, though germination might take time. Its aggressive spreading can be a plus or a minus—perfect for ground coverage but potentially invasive if not managed. This seed mix suits gardeners seeking low-maintenance, pollinator-attracting flowers that thrive in hot, dry conditions.
Pros:- Vibrant, long-lasting blooms attracting butterflies and hummingbirds
- Drought and heat tolerant, ideal for dry climates
- Versatile for ground beds and containers
- Low maintenance, easy to grow from seed
Cons:- Requires full sun for best flowering performance
- Seeds may take time to germinate
- Can spread aggressively, possibly invasive in some regions
Best for: Gardening beginners and those with large, sunny, dry spaces who want a colorful, pollinator-friendly perennial that’s easy to maintain from seed.
Not ideal for: Gardeners expecting quick results or those in shaded or cooler areas where Lantana’s germination and growth may be sluggish or less effective.
- Quantity:300+ seeds
- Plant Type:Perennial
- Bloom Time:Spring through Fall
- Attracts:Butterflies, Hummingbirds, Bees
- Tolerance:Drought & Heat
- Growth Habit:Spreading, ground cover
Our verdict“This seed mix makes the most sense for gardeners seeking vibrant, long-blooming flowers that thrive with minimal watering in hot, sunny areas.”
How We Picked
I evaluated each perennial based on key criteria critical for heat tolerance and flowering performance. These included drought and high-temperature resilience, bloom longevity, ease of planting and maintenance, and value for the price. I also considered the versatility of each plant—whether it’s suitable for ground cover, borders, or containers—and its adaptability to different garden conditions. The rankings reflect a balance between resilience, visual appeal, and overall ease of growth in hot climates, ensuring each option serves a distinct gardening need or preference.Factors to Consider When Choosing Best Heat-tolerant Flowering Perennials
Selecting the best heat-tolerant flowering perennials requires understanding several important factors. Beyond just drought resistance, consider your garden’s specific conditions, your experience level, and how much maintenance you’re willing to do. The right perennial can thrive with minimal water and care, but some may need better soil or more sun exposure to reach their full potential. This guide highlights key considerations to help you make an informed choice that balances durability with visual impact.Climate Compatibility
Ensure the perennial you choose is suited to your local climate, specifically the heat and drought conditions typical of your area. Some plants, like Gazania and Lantana, are native to arid regions and excel in extreme heat, while others may need extra watering or shade. Matching the plant’s native environment with your garden’s conditions reduces maintenance and increases success.
Bloom Duration and Seasonality
Consider how long and when the plant blooms. Some perennials like Gaillardia and Coneflower bloom prolifically for most of the growing season, providing continuous color. Others, such as certain seed varieties, may have a shorter flowering window or bloom only after establishing. Think about your desired visual impact throughout the year.
Ease of Establishment and Maintenance
Seeds are budget-friendly but require patience and care to establish, especially in hot, dry soils. Live plants offer instant display but often come at a higher price point and may need more initial watering or protection. Decide based on your gardening skill level and how much effort you’re prepared to invest for quick results versus long-term growth.
Soil and Sun Requirements
Most heat-tolerant perennials prefer well-drained soil and full sun. Some, like Delosperma, tolerate poor soil conditions and can handle drought without much fuss. Conversely, plants requiring richer soil or partial shade may struggle in harsh conditions, so choose varieties aligned with your garden’s soil quality and sun exposure.
Long-Term Value and Versatility
Assess each plant’s durability over multiple seasons and its versatility—whether it can be used as ground cover, border plant, or container specimen. Some varieties may need to be replaced sooner or are less suited to certain garden styles. Investing in hardy, multi-season performers often leads to better value and less frequent replanting.
Frequently Asked Questions
Can these plants survive a drought once established?
Most of the perennials listed, such as Gazania, Lantana, and Gaillardia, are highly drought-tolerant once their roots are established. Their native adaptations allow them to thrive with minimal water, making them ideal for xeriscaping or water-conscious gardening. Keep in mind that even drought-tolerant plants need some initial watering during the establishment phase, especially in extremely hot climates.
Are seed-grown perennials as reliable as live plants?
Seed-grown perennials like Gazania or Lantana are more affordable and can quickly fill large areas, but they often take longer to establish and may have more variability in bloom timing or color. Live plants provide instant impact and a more predictable appearance right after planting, but tend to be more expensive and require careful handling. Your choice depends on your budget, patience, and desired immediacy of results.
Which perennial is best for a low-maintenance garden?
Plants like Delosperma and Gazania are excellent options for low-maintenance gardens because they thrive in poor soils, require minimal watering once established, and resist pests and diseases. They are ideal for gardeners who prefer to plant and forget, with less frequent pruning or fertilizing needed. However, they may have shorter bloom periods or less fragrance compared to more delicate varieties.
Can I grow these perennials in containers?
Many heat-tolerant perennials, including Gaillardia and Verbena, adapt well to container gardening, provided they receive full sun and well-draining soil. Containers can help control soil quality and water, but they may require more frequent watering and fertilization. Choose compact varieties if space is limited, and ensure your containers have adequate drainage to prevent root rot.
How do I maximize flowering in hot climates?
To encourage abundant blooms, plant your perennials in full sun and amend the soil with organic matter to improve moisture retention and drainage. Deadheading spent flowers can promote new blooms, and applying a balanced, drought-tolerant fertilizer during the growing season supports ongoing flowering. Consistent watering during dry spells, especially in the first year, also helps establish healthy, long-lasting plants.
Conclusion
For gardeners seeking a reliable all-around performer, the Outsidepride Indian Summer Gloriosa Daisy offers excellent color and resilience, making it ideal for most landscapes. Those on a budget or with limited space might prefer seed mixes like Gazania or Lantana, which provide quick coverage at a lower cost. Beginners will find plants like Delosperma or Verbena easiest to establish, thanks to their hardy nature. For those with specific needs, such as ground cover or attracting pollinators, options like Ruellia or Lantana provide targeted benefits. Ultimately, your choice should align with your climate, garden style, and how much effort you want to invest.
