A vigorous, well-branched ornamental sage that’s easy to grow. Blooms all summer and is heat tolerant. The bushy, clump-forming plants are well-branched. Beautiful flower spikes start blooming in late spring to early summer and continue all season. The spikes are lined with pairs of two-lipped, hooded flowers. The blooms have a spreading, open form, are slightly hairy and are highly attractive to bees. Inconspicuous nutlet fruits follow. This appealing salvia grows easily in full or partial sun. Coarse, well-drained soil with average fertility is preferred. It is somewhat drought tolerant once established but performs and blooms best with regular water during the growing season. Soggy soils should be avoided, particularly in the winter. Gentian sage is somewhat cold tolerant and may be grown as a marginal perennial or bedding annual where winters are too harsh. Removal of spent spikes encourages re-blooming and helps to maintain a neat appearance.
