Salvia uliginosa (Bog Sage)

How to grow Salvia uliginosa (Bog Sage) in NZ

Salvia uliginosa (Bog Sage) grows best in full sun or partial shade with fertile soil that retains moisture. Unlike many salvias, this variety enjoys consistently moist conditions and performs exceptionally well near ponds, streams, and low lying garden areas. Incorporating compost before planting will improve soil quality and support strong growth. Water regularly during dry periods, particularly while plants establish. Good sunlight and adequate moisture will encourage vigorous growth and abundant flowering.

Salvia uliginosa (Bog Sage) is easy to care for and requires little maintenance. Regular watering during dry weather helps maintain healthy growth and prolong flowering. Remove spent flower stems if desired to keep plants tidy and encourage additional blooms. Applying a balanced fertiliser in spring will support strong growth and flower production. Cut the plant back in late winter before new growth emerges to rejuvenate the plant and maintain an attractive form.
