Trilliums are spring blooming, shade loving, perennial woodland wildflowers.
They have three dark green, single layer leaves below a green three leaf whorl, below their large three petal flower.

Growing Requirements for Trillium Plants

Trilliums will most likely perish if their foliage is cut from the plant.
There are 30 species of these slow spreading, clumping perennials that are hardy in USDA zones 5-9.
They should be grown in cool, moist soil in partial to full shade.
Plant your Trilliums 12"-18" apart in well draining, acidic, compost rich soil in spring after all danger of frost has passed.
Water thoroughly and regularly until established.

Propagating and Growing Trilliums from Seed

Large Trillium clumps can be divided in mid summer, after all blooms have faded. Trilliums have deep root systems, so be careful, and dig deeply.

Trillium seeds can be sown directly in the garden, in late fall where they will germinate during the second spring.

Starting Trillium seeds indoors is a multi-step process.
The seeds should be sown in a moist growing medium, then placed in the refrigerator for three months.
Remove from the refrigerator and maintain a soil temperature of 60°-70° for the following three months.
Refrigerate again for three more months before returning to 60°-70°.
Germination will take 3 months or longer.
