Trillium is not a common plant as it demands a special environment – it will only flourish if you grow it in a woodland where it can have leafy shade above andmould below. Trillium is certainly attractive when well grown, with all its parts arranged in threes – 3 broad on each stalk, 3 small green sepals and 3 large petals surrounding the central group of golden stamens.
VARIETIES: The favourite species is the Wake Robin (T. grandiflorum) which bears 3 in.– white at first but slowly turning pink with age. The Painted Wake Robin (T. undulatum) is rather similar but smaller, with its 1.5 in. white petals streaked with purple. Similar in height to T. undulatum is T. erectum (1 ft) which bears small wine-coloured blooms.
SITE AND SOIL: A well-drained, humus-rich soil is essential – thrives best in partial shade.
PLANT DETAILS: Planting time August-September. Planting depth 3 in.
Spacing: 1 ft. Height 1-1.5 ft.
Flowering period: April-June.
PROPAGATION: Divide mature clumps in autumn – replant at once.
