Phacelia
Phacelia is a genus of about 200 species of annual, biennial, or perennial herbaceous plants, native to North and South America. Effective at preventing nitrogen leaching and suppressing weeds, they feature pinnately divided leaves and racemes or panicles of tubular or bell-shaped blue, white or yellow flowers. Their eye-catching flowers are an excellent source of high-quality nectar and pollen and are particularly great at attracting bees and other beneficial insects to the garden.
