The Trillium flower is a wildflower that likes shart to part sun. Keep moist and out of direct sunlight if possible. A cool damp location where the plant will receive morning sun is ideal. Do not pick the leaves or petals as it will slot the growth process tremendously and could delay blooming for up to one year.
Keep fallen leaves around the plants as it will provide organic matter and protection against snow. Don't use chemical fertilizers and pesticides, instead apply weak manure tea to surrounding soil.
Keep in the open in the morning and in shade in the afternoon. Requires well-drained humus rich soil. Protect from aggresive plants /animals. Transplant and division them in flower stage.
Be sur to plant in deep, well drained humus rich,acidic to neutral soil, these plants do well in deep to partial shade, mulching annually with leaf mold is also reccomended
Best time to plant in in the fall. Plant in a shady area no direct sun. The soil must be kept moist, but draining. I use an organic fertilizer, fish emulsion.
That depends on which one you are trying to care for some need well drained soil and others need rich watered soil. The best thing for you to do is to either do a net search on them or go to the green house and talk to them about it.
Trilliums are part of the lily family and takes lots of patience. Morning sun(not direct), afternoon shade, good soil and drainage and you should get a leaf the third year of its life with blooms not appearing for five years. Keep area weeded and watch out for the deer! They like lily snacks!
