For those of us who defy the absence of sufficient sun in trying to grow an old fashioned cottage flower garden, this plant is a welcome surprise. Salvia forsskaolii sends up thin wands of delicate violet blue, and its leaves have the effect of woolly hosta plants. In our hot, humid Maryland summers, it dies back after flowering and can make a horrid, black ratty mess; however, fresh new leaves soon appear and all is forgiven. It's great for late summer flowers.

S. forsskaolii is clump-forming in habit with large soft-bristled, lance-like basal leaves of medium green. Long, sturdy spikes of violet-blue tubular flowers, whose lower lips are streaked with white & yellow, rise well-above the plant. This plant works well mid-border in well-drained soil. It is a native of Bulgaria.
