A tall, delicate plant with large, 2-lipped, blue flowers, whorled around the square stem and forming a terminal spike-like cluster. Stiff stems and grayish-green leaves. Special value to native bees.
Prefers moist, gravelly or sandy soils with good drainage. Plant stems may be cut back by up to 1/2 in late spring to promote compactness and prevent stem flopping. Plants may repeat bloom from summer to fall, but need regular moisture to encourage this. Deadhead to promote additional bloom.
A common characteristic of salvia is the presence of a two-lipped calyx and a two lipped corolla. The top lip of the corolla is usually hooded, and the bottom lid is lobed.
