Bog sage

Salvia uliginosa | Rating: 0 votes | Print / Pdf

A large deciduous perennial shrub, salvia uliginosa can very quickly dominate the view near natural water features, like rivers and lakes, but its dominance does not lessen its impressive impact. Commonly known as bog sage, it grows in dense clumps, producing several thin but strong stems, each with an abundance of slender, lance-shaped, deeply veined and serrated light green leaves. In summer, short floral spikes emerge, each producing a multitude of small, deep blue, bi-lipped blossoms with white stripes at its throat. A vigorous spreader via its underground runners, the bog sage thrives in humus-rich, moist soil in full sun. Pruning away drooping stalks invigorates growth.
