The Best Drought-Resistant Flowers

There are various plants capable of surviving periods of drought. Including these plants in a flowerbed adds a bit of color and charm to gardens in hot, dry regions. Drought-resistant flowers also reduce the need for providing extra water during times of little to no rainfall.

Hedge Roses

Hedge roses (Rosa rugosa) also called Japanese roses, are deciduous shrubs belonging to the Rosaceae family. This plant thrives in USDA hardiness zones 3 to 8. This shrub typically reaches heights up to 6 feet and widths up to 5 feet. Hedge roses bloom profusely from June through August. The blooms are fragrant, pure white flowers about 3½ inches across. The glossy, dark green foliage turns various shades of red, orange and yellow during autumn months. This flower is susceptible to powdery mildew, rose rosette, rust and black spot. Potential pest problems include thrips, spider mites, rose midges and aphids. Hedge roses are often used as borders and as hedges.

White Wood Asters

White wood aster (Aster divaricatus) is an herbaceous perennial plant native to the eastern areas of the United States. This aster typically grows well in dry, open areas in USDA zones 3 to 8. White wood aster grows in clumps with dark, sprawling stems up to 2½ feet tall. The leaves are distinctly heart-shaped, coarsely toothed and stalked. Wild wood aster blooms an abundance of 1-inch flowers that have white petals and red or yellow center disks. These flowers attract butterflies during August and September. This plant is commonly used as a border in perennial, wild or native gardens.

Serbian Bellflowers

Serbian bellflower (Campanula poscharskyana) is a sprawling, herbaceous plant native to the Northern Balkans. Hardy in USDA zones 3 to 8, this bellflower exhibits star-shaped, lavender-blue flowers in May and June. Mature plants form low mounds that reach about a foot in height and spread about 1½ feet. The dark green foliage is evergreen to semi-evergreen in warmer winter climates. This drought-resistant flower can be used as edging for border fronts, paths and rock gardens.

Prairie Coneflowers

Prairie coneflowers (Ratibida columnifera), also called Mexican hats, are long-head coneflowers in the Asteraceae family. Indigenous to the area from New Mexico to British Columbia, this flower tolerates both drought and somewhat poor soils. This herbaceous perennial is a hairy, erect, clump-forming plant that reaches heights of 3 feet. The daisy-like flowers have yellow to brown-purple rays with dark brown center disks. These flowers generally bloom from June until September. Prairie coneflowers work best when massed or grouped because of their sparse leaves.

Indian Blankets

Indian blankets (Gaillardia pulchella) also called blanket flowers, are hairy annual wildflowers belonging to the daisy family (Asteraceae). Native to Mexico and the south-central U.S. regions, this flower thrives in the dry summer heat and can tolerate poor soils. Indian blankets typically grow from 1 to 1½ feet in height and have upright stems. The daisy-like flowers feature rayed petals in shades of yellow and red surrounding dark purple center disks. The flowers bloom from June until the first frost. Indian blankets are often used in mass plantings for borders, flower beds and rock gardens.

Treasure Flowers

The treasure flower (Gazania rigens) is an African daisy that thrives in USDA zones 9 to 11. These flowers bear dandelion-like leaves in silvery-green tones. The stems are typically 6 to 10 inches tall and topped by a single, daisy-like flower. These flowers have petals in shades of orange, yellow, white or bronze with black eyes at their bases and orangish-brown center disks. Treasure flowers bloom from summer until the first frost, and make attractive plants for hanging baskets because of their trailing stems.
