Full Sun Plants
The best plants for full sun gardens — heat-tolerant perennials, shrubs, annuals, and ground covers that thrive in 6–8+ hours of direct sunlight.
☀️Full Sun Perennials
Coneflower (Echinacea purpurea)
Native North American wildflower with pink-purple petals and spiky orange-brown center cones. June–September bloom. Drought tolerant once established. Leave seed heads for goldfinches in winter. Zones 3–9. Attracts butterflies and bees. Self-seeds to naturalize.
Black-Eyed Susan (Rudbeckia)
Golden yellow flowers June–September. Extremely heat and drought tolerant. Self-seeds prolifically. Native to much of North America. Short-lived perennial but perpetuates itself. Full sun to part shade. Pairs beautifully with ornamental grasses.
Russian Sage (Perovskia)
Silver-white stems with masses of tiny lavender-blue flowers July–September. Extremely drought and heat tolerant — thrives in conditions that wilt most plants. 3–5 ft. Zones 5–9. Deer resistant. Winter interest with silver stems.
Sedum 'Autumn Joy'
Succulent foliage all season, flat-topped pink-to-rust flowers September–October. Full sun. Zones 3–9. Nearly zero maintenance. Drought tolerant. Winter interest with bronze seed heads. One of the best low-maintenance full-sun perennials.
Lavender (Lavandula)
Fragrant gray-green foliage with purple flower spikes June–August. Full sun essential — needs 6+ hours minimum. Excellent drainage required. Zones 5–9. Deer and rabbit resistant. Attracts bees intensely. Culinary and fragrance uses.
Daylily (Hemerocallis)
Outstandingly heat and drought tolerant once established — one of the toughest sun perennials. June–August bloom. 1,000+ cultivars. Reblooming varieties extend season. Zones 3–10. Nearly indestructible. Full sun for best bloom count.
Catmint (Nepeta)
Silver-gray aromatic foliage with blue-purple flowers May–June, reblooming August–September when cut back. Full sun to part shade. Deer and rabbit resistant. Zones 4–9. Excellent edging plant. Attracts bees.
Coreopsis
Bright yellow or pink flowers June–September — one of the longest-blooming perennials. Extremely heat and drought tolerant. Full sun. Zones 4–9. Fine-textured foliage. 'Moonbeam' (pale yellow) and 'Limerock Ruby' (deep red) are popular cultivars.
🌳Full Sun Shrubs
Butterfly Bush (Buddleja)
Fragrant cone-shaped flower spikes June–October in purple, pink, white. Heat and drought tolerant. Full sun. Zones 5–9. Attracts butterflies and hummingbirds. Choose sterile cultivars (Pugster, Lo & Behold) to prevent invasive seeding.
Knockout Rose
Blooms May through frost with zero deadheading. Disease resistant — no black spot. Heat tolerant. Full sun (6+ hours). Zones 4–9. 3–4 ft. Red, pink, yellow, coral. The rose that eliminated the need for rose care.
Caryopteris (Blue Mist)
Blue to purple flowers August–September — valuable for late-season color when most shrubs have finished. Silvery-gray foliage. Full sun. Zones 5–9. Drought tolerant. Deer resistant. Cut to 6–12" in spring.
Potentilla (Cinquefoil)
Yellow, orange, pink, or white flowers May–September on compact 2–4 ft shrubs. Full sun. Zones 2–7. Extremely cold hardy. Drought tolerant. Deer resistant. Low maintenance. One of the longest-blooming shrubs.
Lilac (Syringa)
Intensely fragrant purple, pink, or white blooms in May. Full sun essential — poor bloom in shade. Zones 3–7. Long-lived. Prune immediately after flowering only. Cold winters required for best bloom.
🌻Full Sun Annuals
Zinnias
Heat-loving workhorse annual. Electric colors from June through frost. Direct sow after last frost — transplanting stunts them. Deadhead for continuous bloom. Heat and some drought tolerant once established. Attracts butterflies and hummingbirds.
Portulaca (Moss Rose)
Succulent annual that thrives in poor, hot, dry conditions. Jewel-bright flowers in red, orange, yellow, pink, white. Full sun. Perfect for parking strips and hellstrips where nothing else grows. Almost indestructible in heat.
Marigolds
Full sun essential — shade produces all foliage, few flowers. Heat tolerant. Companion planting benefit against nematodes. French marigolds (6–12") for borders; African (18–36") for back of bed. Long bloom May–frost.
Lantana
Tropical annual (perennial in Zones 9+) with extreme heat and drought tolerance. Clusters of tiny multicolor flowers. Hummingbird and butterfly magnet. Toxic to pets. Thrives in conditions that kill most annuals.
Sunflowers
Love maximum heat and sun. Direct sow only — roots hate disturbance. Giant types (Mammoth) to 12+ ft; dwarf types for small spaces. Edible seeds. Self-seeds prolifically. One of the easiest full-sun plants to grow from seed.
🌱Full Sun Ground Covers
Creeping Thyme (Thymus)
Evergreen, drought-tolerant ground cover with tiny pink or white flowers in summer. Tolerates light foot traffic — releases fragrance when walked on. Full sun. Zones 4–9. Height 2–4". Perfect between stepping stones, along paths, and in hot dry spots.
Sedum (Stonecrop)
Succulent ground covers thriving in hot, dry, poor-soil conditions. Various types for different purposes: low creeping types (acre, rupestre) for slopes; upright clumping types (Autumn Joy) for borders. Full sun. Zones 3–9. Excellent for hell strips and parking areas.
Creeping Phlox (Phlox subulata)
Explosion of spring flowers in April–May — pink, purple, white, red. Evergreen spreading mat. Full sun. Zones 3–9. Spreads 24" wide. Excellent for slopes, rock walls, and edging. Drought tolerant after establishment.
Prairie Dropseed (Sporobolus)
Native ornamental grass ground cover in full sun. Fine texture, arching form. Late summer fragrant flowers with scent of buttered popcorn. Drought tolerant. Zones 3–9. Low maintenance once established. Beautiful year-round presence.

Full Sun Plants — FAQs
What plants thrive in full sun all day?
Plants that thrive in all-day full sun (8+ hours): coneflower, black-eyed Susan, daylilies, lavender, ornamental grasses, sedum, zinnias, marigolds, portulaca, sunflowers, lantana, Russian sage, Knockout roses, and butterfly bush. Key trait: drought tolerance is essential for full-sun plants since sunny spots dry out quickly.
What is the difference between full sun, part sun, and part shade?
Full sun = 6+ hours direct sunlight (ideally 8+ hours). Part sun = 4–6 hours direct sun. Part shade = 2–4 hours direct sun, or dappled light all day. Full shade = less than 2 hours direct sun. Many plants labeled 'full sun' will tolerate part sun but may bloom less heavily. Heat also matters — 'full sun' in Zone 3 is very different from full sun in Zone 9.
What low-maintenance plants grow in full sun?
Lowest-maintenance full-sun plants: ornamental grasses (cut once/year), sedum (no care once established), daylilies, coneflower, black-eyed Susan, Knockout roses, creeping thyme, and Russian sage. These all tolerate drought, require no deadheading or regular fertilizing, and multiply or maintain themselves over years.
What full sun plants are drought tolerant?
Best drought-tolerant full-sun plants: Russian sage (excellent), portulaca (drought-proof), sedum/succulents (drought-proof), creeping thyme (drought tolerant), lavender (needs excellent drainage + dry conditions), ornamental grasses (most are drought tolerant once established), coreopsis, black-eyed Susan, and lantana. These plants evolved in dry conditions and don't want regular watering once established.
What can I plant in a hot south-facing border?
South-facing borders get the most intense heat and sun. Best choices: lavender (prefers hot and dry), Russian sage, ornamental grasses, sedum, creeping thyme, zinnias, marigolds, portulaca, lantana, agastache (hyssop), and ornamental alliums. Avoid plants that need moist soil or won't tolerate heat/drought — they'll struggle. Mulch heavily to conserve moisture.
