Big Blue Salvia
Salvia longispicata x farinacea. This impressive Salvia was a show stopper in field trials, with tall spikes of true blue flowers that attracted bumble bees and other bees from mid-summer to the first frost. It bloomed right into late October in our trials. The deep green foliage beneath the flowers is thick and lush and totally trouble free. Big Blue Salvia is an interspecific hybrid, and the first of its type to flower from seed in the first year. No deadheading or further care is needed. It performs best in full sun, but will tolerate dappled shade, and grows 60-90cm (24-36") tall in beds or large containers. Space the burly, drought tolerant plants 40-45cm (16-18") apart.
Annual - can be grown as a perennial with winter protection
