Description
Salvia uliginosa is an herbaceous perennial growing up to 3 to 6 feet (0.91 to 1.83 m) tall in one season, with multiple thin stems and yellow-green lance-shaped leaves that have serrated edges. The plant quickly spreads on underground runners and is readily divided.
The bright azure-blue flowers are .5 inches (1.3 cm) long with a white beeline in the throat pointing toward the nectar and pollen. They grow in whorls beginning in summer until fall, with many flowers coming into bloom at the same time.
Cyanosalvianin, the blue pigment from the flowers of S. uliginosa, is a metalloanthocyanin, a complex formed of six molecules of the anthocyanin type, six molecules of the flavone type and two magnesium ions.[2]
Cultivation
Salvia uliginosa was introduced into horticulture in 1912, and has become popular in gardens and public landscapes for its azure-blue flowers, ability to grow under various conditions, and its pollinator habitat attributes.[1]
This plant has gained the Royal Horticultural Society's Award of Garden Merit.[3][4]
