Trillium undulatumAlso known as:
The flower of the painted trillium is probably the most attractive of any in the genus. It appears on a short stem above the leaves, it is white with a deep pink center and ruffled edges, hence the botanical name undulatum which means wavy.
Trillium undulatum is a true woodland beauty. It is particularly heat intolerant and requires a very acidic environment. The soil should be rich, well drained yet consistently moist. Best planted in open shade or with a north facing exposure where it will be protected from sun and heat. Best planted in groups, it blooms in late spring, April to May. One of the hardiest Trilliums: zones 3-7
Established clumps can be divided in summer. Slow to propagate from seed.
Once established, Trillium undulatum will form a clump with an increasing number of flowers. Mulching will help maintain adequate moisture and acidity levels. All members of the Trillium genus have leaves and petals that grow in multiples of three, hence their botanical name.
