Faits intéressants
Biennial Gaura is easy to identify from the nodding tip of the stem and club-shaped fruit. It generally appears in drier locations, like dry, sandy and rocky areas. It is an excellent drought-tolerant plant that is great for dry sunny gardens. Unlike many evening primroses, this species spreads gradually by underground rhizomes, forming small colonies. Flowers attract native bees, butterflies, and moths.
