Trillium chloropetalum (Giant Wake Robin)
Giant Trillium, Giant Wakerobin, Giant Wake Robin, Wood Lily, Trinity Flower
Rich with a rose fragrance, Trillium chloropetalum (Giant Wake Robin) is an incredible beauty with a great garden presence. Poking from the soil in winter, large buds send up stems topped with egg-shaped leaves, slightly mottled with chocolate brown. Resting in their center in early to mid-spring is a large three-petaled flower of white, yellow, or deep purple-black. Long-lived, spreading slowly, and taking several years to form a significant clump, trilliums are worth the wait! Trillium chloropetalum is native to California.
- This clump-forming perennial grows up to 12-18 in. high and wide (30-45 cm) and will spread slowly if left undisturbed.
- Performs best in part shade or full shade, in fertile, humusy, moist, well-drained soils. Drought tolerant once established.
- Excellent when massed in a shaded woodland garden, naturalized area, or wildflower garden. Great as a ground cover too!
- Because trilliums go dormant by midsummer, pair them with other shade-loving perennials that will look good the rest of the gardening season and share their place until they reappear the following spring.
- Generally disease free, this plant requires little maintenance. Watch out for slugs and snails.
- The best time for planting is late summer or early fall as it gives the rhizomes time to establish good root systems before the following growing season.
- Propagate by seed in pots in a shady cold frame as soon as seed is ripe; takes 5-7 years to reach flowering size. Propagate rhizomes by division after flowering
- Native to California, Oregon, and Washington.
