Trillium chloropetalum is a California native with marbled, clover-like foliage, which contrasts with three-cornered, burgundy flowers from late spring to early summer. The foliage looks good long after the flowers are over. This is a superb plant for a woodland garden, and it associates well with plants such as erythroniums, which like the same conditions. Once established it dislikes disturbance.
