Large Flowered Trillium, also called White Trillium, is easy to grow and will return faithfully year after year in optimal conditions, spreading gradually by seed if left undisturbed. The flowers become pink-tinted later in the season, and finally give way to berry-like capsules. The foliage of this ephemeral will die-back to the ground by midsummer. White-Tailed Deer eat both the foliage and flowers which may be popular with deer because of the large, highly visible bloom.

Trillium Grandiflorum does best in partial shade among, deciduous hardwood trees. The leaves of the trees provide the perfect mulch. Soil that is moist but well-drained and high in organic matter is best. Trilliums will grow in clay soil, as long as the soil is not too heavy or wet. Space the bare root plants about 6 to 12-inches apart and about 2 to 4 inches deep. Trilliums can take a few years to become fully established.

Planting and Cultivation Notes
We recommend planting ephemerals in early fall while the soil is still warm, or in early spring. Spring installations will have some time to develop before summer dormancy, but will not produce flowers the first year. An early fall planting allows the roots time to establish properly before winter, and gives the plants a stronger start the following spring. This woodland species appreciates a generous application of leaf mulch in the fall.
