Oyster plant is a short-stemmed, tender foliage plant that makes attractive, small, dense, spreading clumps. It forms a solid groundcover of upright leaves. The 6 to 8 inch long, sword-shaped leaves are green above and purplish below. The unusual flowers, borne down among the leaves, appear as clusters of tiny white flowers nestled within two boat-shaped, purplish bracts. They are not noticeable unless you look closely.
