Stinging annual lupine (Lupinus hirsutissimus) is a bristly, erect wildflower from the coastal mountains of Southern California and Baja California, found on dry slopes, chaparral and recently burned ground. Its stiff hairs sting skin, so it is grown mainly as a wild or native plant rather than a garden favourite.
