What is TRILLIUM?

(Three-leaved Nightshade, Trinity Flower, or WooD-LiLY. Nat. Ord. Liliaceae). This is a useful genus of hardy tuberous-rooted perennials suitable for border or rock garden culture. They require plenty of peat in the soil, which should nevertheless be light, and though they prefer a little shade, a sunny position will suit them. Propagation by seeds in the summer, and root division in the autumn or spring (at which last period they are best planted), is not a matter of very great difficulty, though there are some plants, it is true, which are easier to increase than these. Paxton says that the roots of all species are violently emetic. What to Grow.We recommend the following speciesthe dwarfer ones for rock garden purposes : Trillium californicum.Syn.
