Formerly Kochia scoparia. Native to Eurasia. To 3 ft. high and 2 ft. wide. Branches are so thickly clothed in soft, narrow, light green leaves that plant is too dense to see through. Grow individually for its gently rounded form; or group plants for low, temporary hedge or edging. Can be sheared into any shape. Grow from seed sown in early spring or (in mild-winter climates) in fall. Seeds need light to germinate, so barely cover them with soil. Tolerates high heat.
B. s. trichophylla known as Mexican fire bush or burning bush, is identical to the species, but its foliage turns bright red or purplish red in autumn. Can reseed profusely enough to become a pest; be sure to hoe out any unwanted seedlings when they're still small.
