Salvia uliginosa
Salvia uliginosa originates from moist places of southern Brazil, Uruguay and Argentina, and is often referred to as the bog sage. It was described and named by English botanist George Bentham in 1833, (ulignosa meaning of swamps and marshes), but was not introduced into cultivation in Britain until the early part of the twentieth century.
The stunning sky blue flowers, flecked white, of Salvia uliginosa are a wonderful addition to the late summer/autumn borders, and can be seen in the Four Seasons Garden (area B on the downloadable map) and also on the Main Borders along the Broadwalk. Graceful, branching 6 ft stems are set with narrow, toothed leaves. It flowers continuously from September to November until the first frosts destroy them, and is well worth its Award of Garden Merit status from the Royal Horticultural Society.
