Trillium erectumAlso known as:
Though the flowers of Trillium erectum are usually in shades of purple or crimson, they will sometimes tend towards light pink, and even whitish hues. The three petaled flowers appear mid to late spring, on 3" stems above the leaves, and will last for up to 3 weeks before giving way to fleshy berry-like fruit. The leaves can be up to 8" long, and across. The foliage dies back mid to late summer, when the plant enters dormancy.
Red trillium grows in deciduous forest, but likes being exposed to some direct sunlight early in its growing season. It prefers rich, organic, acid, well drained soil that remains consistently moist. Best planted in groups, it blooms mid to late spring, April or May. Combines beautifully with Phlox divaricata. One of the hardiest of trilliums: zones 3-7
Established clumps can be divided in summer. Slow to propagate from seed.
Once established, red trillium will form a clump with an increasing number of flowers. Mulching will help maintain adequate moisture and acidity levels. It has a slightly malodorous smell which it uses to attract its pollinators. All members of the Trillium genus have leaves and petals that grow in multiples of three, hence their botanical name.
