Bog Sage

Originally from South America, bog sage (Salvia uliginosa) is very showy throughout the summer and well into the fall with its sky blue flowers. This salvia grows vigorously in my garden’s average, well-drained soil. It spreads from underground stolon-like runners and grows to about 4 feet in height. Its stems are thin and elegant, so to lend them support I cage the plants early in the season to keep them from falling over. If the plant grows beyond the cage, as it often does, and becomes disheveled, I cut it back severely and it will respond quickly with a flush of new growth.
