In the garden

Trillium erectum 'Ochroleucum', or 'Viridiflorum' is a perennial herbaceous member of the genus Trillium native to New Brunswick, Nova Scotia, Ontario and Quebec. In the UK it is valued for its spring display, reliably producing blooms in April to May and forming a compact plant of around 0.4 m in height. Select a site that holds moisture without becoming waterlogged: the cultivar adapts to sandy, loamy or clay soils provided they are moist but well-drained. It will tolerate conditions from full sun to full shade, so placement can vary from brighter open beds to shadier positions where soil moisture is retained. Hardiness is H7 (fully hardy) and it also fits within USDA zones 4–9, so it withstands typical UK winters when planted in a suitable, sheltered spot. Use the plant where a low, spring-flowering perennial is wanted; it can be integrated into mixed borders or areas that receive early-season light before taller perennials leaf out. Give it consistent moisture through the growing season and you can expect its spring flowers at roughly 0.4 m above ground in April to May.
