Nursery contributed plant descriptions

Pycnanthemum incanum is a beautiful mountain mint growing to about 3 feet high on square stems topped with clusters of white to pale lavender flowers subtended by icy white-frosted bracts. The leaves smell strongly of spearmint and can be used to flavour teas or is said to repel mosquitoes if rubbed on the skin. Mountain mints are the pollinator attractor to end all pollinator attractors surrounded during its mid to late summer bloom in buzzing, fluttering clouds of butterflies, moths and bees. Clumps, does not spread.
