The intense rich blue flowers of Blue Sage bring color to the darkest days of the year. Native to northern India into China, its a modest plant in containers yet a vigorous grower during the summer, and with a little pruning it creates a well branched specimen. Flowering for us from December through February, the flower heads continue to produce flowers over and over again for weeks at a time. Since it is a winter bloomer, it responds to the shortening days of late summer and fall so pruning is best done before the height of summer.
