Trillium grandiflorum

The woodlands of eastern North America are the native home of these exquisite small perennial plants, also known as wood lilies or wake robin. Their three-petalled, pure white flowers appear in late spring above a trio of widely oval, veined, shining leaves high on the stalk.

Trilliums like deep, moist, peaty, acid soil and I have most often seen them naturalized in woods in Scotland, Wales,

Yorkshire, Devonshire and other parts of Britain with this kind of soil, notably in the National Trust garden of Knightshayes Court, in Devonshire, where a woodland is underplanted with small herbaceous treasures, as well as with peat-loving shrubs. These are ideal conditions, but trilliums do not demand them, and can be easily grown in any dampish place so long as there is no lime in the soil, which is poison to them. They have been grown for many years in the town garden of an alpine specialist in Birmingham, who has them in the shade of rhododendrons. He told me that the key thing is not to cosset them but to leave them alone.

There is a pink form of this plant and a rare double form, of which the flowers have been likened to camellias, but it is not vigorous.

Plant trilliums 12 inches (30 cm) apart in good lime-free soil.
