Cult. The most part of the species of Gaura are little better 

 than biennials, although some are marked perennial. A light 

 soil suits them best, and they are only to be propagated by 

 seeds, which should be sown early in spring in the open ground. 

 Those species natives of Mexico will require a little protection 

 in winter the" first year from seed.
