Trillium is threatened in its native habitat due to the overly enthusiastic harvesting of wild plants. So buy only from reputable dealers (local or online) that specify their plants are propagated from cultivated stock. These no-fail perennial plant combinations are perfect for landscaping.
Trillium Care Must-Knows
Trillium grows best in part shade or full shade. It likes moist, well-drained, humus-rich soil, a condition that when met encourages the plant to gradually multiply and spread. (It does not like to be transplanted.) In spring, plant specimens about 4 inches deep, then water regularly during the first year after planting. Each fall, spread a mulch of rotted leaves over the plant’s root zone. This woodland gem sometimes requires 5 or more years in the same growing site before blooming, a worthwhile wait. It often dies down to the ground by late summer, even earlier in areas with dry soil. Pair trillium with ferns, hostas, astilbes, and other perennials that will cover the bare space left in your garden when the plant goes dormant. Try these other spring flowers in your garden.
