Flowers That Tolerate Heat

The heavy heat of summer is a death sentence for many flowers, causing them to shrivel up and turn brown within days or even hours. Though some flowers won't do well with too much sun, others with tolerate and thrive in the heat, producing their healthiest, flashiest blooms.

Annual Lion's Ear

A member of the mint family, annual lion's ear (Leonotis nepetifolia) is a tall growing annual that boasts a stiff, dark green stalk and clusters of deep orange flowers. Annual lion's ear is no stranger to heat: the plant is a native of subtropical and tropical Africa. The drought tolerant plant does best in full sunlight or dappled shade in USDA zones 8 to 11. Though not picky about soil, annual lion's ear should be watered occasionally to keep the blooms looking fresh. The plant is known for attracting hummingbirds to its nectar-rich flowers.

Blanket Flower

A native of the American South, blanket flower (Gaillardia x grandiflora) is a hardy perennial that thrives in disturbed, sandy soils under the hot sun. In mid-summer until fall, the plant exhibits stunning sunflower-like blooms in hot pink and yellow. Growing best in USDA zones 4A to 8A, blanket flower requires very little care once established. Though adaptable, for best results the plant should be grown in well drained, neutral soil. Water the plant occasionally during summer droughts to promote healthy flowers.

Whorled Coreopsis

Whorled coreopsis (Coreopsis verticillata) is a bush perennial, native to the Southeastern United States. Drought tolerant and sun hungry, the summer blooming whorled coreopsis boasts wiry, blue green foliage and pale to bright yellow flowers (depending on the cultivar). The plant is well suited for USDA zones 5 to 10. Grow whorled coreopsis in well-drained soils in full sunlight. The plant requires little watering. Deadheading spent flowers will help keep the sunny plant blooming long into the summer.
