The 'Black Pearl' Ornamental Pepper (Capsicum annuum) is the first-ever black-leaved ornamental pepper. Black foliage and clusters of black, shiny pearl-like peppers make it a centerpiece in the garden or containers. It grows to 20 inches tall and 19 inches wide and develops an attractive pyramidal shape. The plant is exceptionally heat-tolerant and disease-resistant. (Caution: The peppers, which turn red with maturity, are edible but extremely hot.)
