High Plains Gardening
The gardening website of the Texas High Plains Region
Rounded mounds of green leaves on multi-forked stems put forth multitudes of fragrant purple/magenta flowers from summer into autumn. Flowers open in late afternoon (perhaps around four o'clock) and close in early morning. Cold hardy and heat and drought tolerant, after freezing in the fall, the top growth breaks away. Desert four o'clock emerges in the spring from a large root. Will not transplant well once established. Southwest native perennial is usually found in somewhat shaded areas.
Birds, bees, butterflies and hummingbirds are attracted to this uselful, long blooming native. Shaded areas in habitat, pollinator, native, high desert and xeric landscapes are typical locations gardeners should use it in. As desert four o'clock will spread up to 3 feet, draping over a wall provides a good effect.
It may be necessary to keep the stems trimmed back from covering other plants.
