White Indigoberry is an evergreen shrub or a small tree with glossy, bright green leaves and small, white flowers. It has a narrow, upright form and nearly horizontal branches and thorns at the bases of the leaves. The curious name comes from its edible fruits, which are white but contain a dark blue pulp. The fruits have been used to make a blue dye and ink. It is native to southern Florida and tropical America. It occurs mainly in forests and thickets along the coast and is tolerant of wind, salt and sandy soils. It is grown in South Florida for its dense form and its stiff, nearly horizontal branches which give it a geometric form. It can be used as a hedge, a specimen plant and in coastal landscaping. The fruits provide food for birds.
