Flowers That Tolerate Sun in Texas

Home to lush hill country, rapid rivers and the Guadalupe Mountains, Texas is a vast state with tremendous biodiversity. The second largest state in the United States, Texas boasts many beautiful flower species that can be grown in home gardens throughout a range of climate zones. There are a number of flowers that can be grown in the hot Texas sun with good results.

Annual Phlox

Annual phlox (Phlox drummondii), also called garden phlox, is an annual native to Central and Eastern Texas. The spreading plant offers loose green foliage and five-lobed flowers in colors ranging from hot magenta to pure white or lilac. Annual phlox is low maintenance, and does well as a bedding or border plant. Annual phlox also works well as a ground cover, as the plant rarely reaches a height above fifteen inches. The plant grows in a number of regions, from U.S. Department of Agriculture planting zones 3 to zone 10. Annual phlox is a good candidate for Texas heat, as the plant requires full sunlight to look its best. Annual phlox ideally should be planted in a sandy, well-drained soil that is watered frequently.

Blue-eyed Grass

A member of the iris family, blue-eyed grass (Sisyrinchium angustifolium) is a perennial plant that boasts long, grass like leaves topped with tiny "true blue" flowers. Blue-eyed grass grows in low clumps, reaching a maximum height of about twenty inches. The spring and summer blooming plant is native to a wide region that spans from Newfoundland and Quebec down to Eastern Texas. The plant does well in containers and in borders in USDA zones 3 to 10. Blue-eyed grass requires virtually no care, thriving in sunny, hot locations in just about any type of soil. Once established in its native region, blue-eyed grass requires no water other than whatever comes from the sky.

Texas Sage

Texas sage (Leucophyllum frutescens), also called silverleaf, is a species of shrub native to Texas. The plant sports dense silvery green leaves and small blooms, which range in color from white to pink or lavender depending on the cultivar. The spring blooming shrub reaches an average height of between 4 to 9 feet. Commonly planted as a hedge or screen plant, Texas sage is well suited to the hot Texas sun and can be grown in full sunlight in USDA zones 7B to 10A. The shrub isn't picky about pH, growing in alkaline, acidic or neutral soils so long as they're well draining. The plant should be watered on a regular basis for best results.
