Gaura is a spring to late fall bloomer that requires mostly sun and the blooms appear all along each thin but resilient stem. When the breeze catches it, it's just so pretty.
After blooming (late fall/early winter), I hack it back aggressively using no particular technique.
While this plant grows nicely here in our warm and humid Virginia climate, it is also quite drought tolerant. So for my friends and readers in the Southwest who are accustomed to only growing desert-loving succulents, you might give gaura a try.
