Twinkling in shady corners of the garden, the broad, milky-white blooms of Trillium ‘Grandiflorum’ are set off beautifully by a backdrop of lush, ribbed foliage. ‘Trillium’ means ‘triple lily’, in reference to the petals, bracts and leaves being produced in distinct trios.
Growing naturally in woodland environments, these hardy perennials relish moist, humus-rich soils in shade, making excellent companions to hellebores, snowdrops, and anemone nemerosa.
Trillium ‘Grandiflorum’ takes some time to fully establish but you will be richly rewarded for your patience. This variety has earned itself a coveted RHS Award of Garden Merit for its reliability and robust nature.
Grow Trillium in a shaded, well-drained area with neutral to acid soil. Woodland areas where the soil is naturally moist and rich in leaf mould suit these unusual plants best.
Plant the corms 7.5cm deep, spaced 30cm apart in the soil. Provide consistent watering, ensuring the soil stays evenly damp.
May be slow to establish, however Trillium are well worth the wait for their lush carpets of exquisite, marbled foliage and large 3-petalled flowers in early summer.
An annual mulch with leaf mould will feed the plants sufficiently, retain soil moisture levels and help to suppress weeds.
