When summer heat drags on, and the forecast has no mention of rain, even well-tended gardens will struggle. Plants wilt, soil cracks, and water bills rise fast. Water scarcity is the reason more gardeners are turning to drought-resistant plants. These species survive in dry conditions without constant watering or care.
This list highlights 10 drought-resistant plants that will remain healthy even during prolonged periods of heat. These plants feature deep roots and water-storing leaves. Plus, they slow their growth to survive the drought better.
Native Perennials That Can Handle Dry Summers
Native perennials are well-suited for harsh summer climates because they’ve developed deep root systems, specialized leaf structures, and efficient water-use mechanisms over centuries of adapting to local conditions. These plants have evolved in local conditions and typically have a better chance of survival than imported varieties. The Missouri Botanical Garden offers regional lists of drought-tolerant native plants that thrive without irrigation.
- Purple Coneflower (Echinacea purpurea)
This perennial develops a deep taproot that reaches moisture far below the surface. It tolerates the hot sun, thrives on dry soil, and resists high winds. Plant coneflowers in areas with full sunlight and well-draining soil. Once established, the plants will need little irrigation. - Blanket Flower (Gaillardia)
Blanket flowers grow in dry, sandy soils where other species struggle. Its hairy leaves can hold moisture, while its roots grow deep enough to draw water from compact ground. Blanket flowers bloom throughout summer without the need for plenty of water. - Black-Eyed Susan (Rudbeckia hirta)
This wildflower thrives in lean soil with little care. Its strong stems resist drooping during drought. Meanwhile, the roots thrive in dry conditions and will return year after year. Plant in full sun and ensure sufficient space for adequate airflow.
Succulents That Store Their Own Water
Succulents are among the most reliable, drought-resistant plants for gravel beds, containers, and dry slopes. They hold moisture inside their leaves or stems, making them perfect for hot, dry weather.
- Sedum (Stonecrop)
Sedum holds water in its thick leaves and can survive for weeks without rain. It grows well in rocky soil and withstands the full sun without wilting. Sedum spreads slowly and covers dry areas with little effort. - Hens and Chicks (Sempervivum)
This succulent forms compact rosettes that seal in collected moisture. It grows in shallow, gritty soil and can resist drying winds. Once planted, it spreads naturally and thrives with minimal water.
Herbs That Love the Dry Heat
Many culinary herbs grow best in hot, dry weather. These plants evolved in arid climates to continue producing during drought. The University of California Master Gardener Program explains how to care for herbs in low-water gardens using natural methods.
- Lavender (Lavandula)
Lavender’s silver leaves reflect sunlight to limit moisture loss. Its roots go deep and can locate water that other plants miss. Lavender prefers dry, rocky soil and will suffer more from overwatering than from drought. - Thyme (Thymus vulgaris)
Thyme grows close to the ground and needs little water to stay healthy. Its tiny leaves lose very little moisture. Plant it in full sun with fast-draining soil, and trim often to keep it dense. - Oregano (Origanum vulgare)
Oregano spreads wide and shades its roots to stay cool. It grows in rocky soil with no need for fertilizer and endures dry weather without fading. Harvest the leaves often to promote fresh growth during summer.
Shrubs and Grasses That Endure Dry Seasons
Shrubs and ornamental grasses are valuable drought-resistant plants that add height and protection to dry-climate gardens. These varieties use deep roots and sturdy growth to resist heat and moisture loss.
- Russian Sage (Perovskia atriplicifolia)
Russian sage has woody stems and narrow leaves that stay firm in dry heat. It grows in poor soil, resists pests, and continues to bloom well into late summer. Cut it back every spring to shape new growth. - Switchgrass (Panicum virgatum)
Switchgrass forms dense roots that stretch deep into the soil. This helps it stay upright and green during long dry spells. It tolerates poor soil and supports pollinators and birds throughout summer.
Drought-Resistant Plants That Make Summer Gardening Easier
Hot weather doesn’t have to mean fewer plants. By selecting drought-resistant plants that suit your region and soil type, you reduce stress on your garden, save time, effort, and water. These plants survive tough summers by adapting underground or slowing their growth above it.

FAQs
What makes a plant drought-resistant?
These plants store water, grow deep roots, or reduce leaf moisture loss so they survive longer without irrigation.
Can I grow drought-resistant plants in containers?
Yes. Use succulents or herbs with well-drained soil. Avoid overwatering and place containers in full sun.
Should I mulch around drought-resistant plants?
Yes. Mulch helps retain moisture, protect roots, and reduce soil temperature, even for drought-tolerant species.
How long does it take for drought-tolerant plants to become low maintenance?
Most plants take one full season to establish. After that, they need little more than seasonal trimming.
