TRILLIUM(WAKE ROBIN, WOOD LILIES)Family: LILIACEAE
This genus includes 30-50 species primarily distributed in Asia and North America. Mostly spring blooming and, with a few exceptions, deciduous woodland plants. They have underground rhizomes; some species develop a many-stemmed clump, others a dense colony. Whorls of foliage and solitary flowers in white, yellow, green, brown, rose or purple, occasionally bicoloured. After flowering, a fleshy berry is formed. Most species are long lived ornamentals. For optimum growth give them a deep, moist soil in bright, half or fully shaded conditions. They will, however grow in less than ideal conditions.
