It was described and named by botanist George Bentham for its typical habitat "of swamps and marshes", or uliginosa.

[1] 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 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.

[2] 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.
