Trillium ovatum (Western Trillium)

Trillium ovatum (Western Trillium) is a vigorous clump-forming perennial with erect stems clad with a whorl of 3 broadly ovate leaves. From the center of the leaf whorl emerges a solitary, pure white flower in late winter to late spring, adorned with 3 recurved petals and golden yellow anthers. Long-lasting, the large and charming blossoms turn pale pink as they age and give way to berry-like capsules. Western Trillium is a very long-lived species that is primarily pollinated by beetles, moths, and bumblebees. Easy to grow, this graceful Trillium is a lovely choice for wildflower gardens or woodland gardens.

• Grows up to 10-18 in. tall (25-45 cm) and 8-12 in. wide (20-30 cm). Will spread gradually if left undisturbed.
• Performs best in part shade or full shade, in deep, humus-rich, acid to neutral, moist, well-drained soils. Keep well watered during dry weather in spring and early summer. Mulch in fall with leaves.
• Excellent when massed in shaded beds and borders, underplanting shrubs or roses.
• 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.
• Propagate by rhizome division (in fall) or seed. Seeds do best when planted outdoors soon after fruits have ripened. 1 month stratification is necessary.
• Young plants can take 3-5 years to bloom and another 5-8 years to develop into a lovely clump.
• Native to western North America
