About Trillium
Everything comes in threes, which is where the name is from. Extremely slow from seed, often seven years to flower, which is why wild-collected plants still appear in trade. Buy only from a nursery that states the plants are propagated, never collected.

Common questions about Trillium
- Is Trillium deer resistant?
- Trillium (Trillium sp.) is rated Seldom Severely Damaged on the Rutgers NJAES four-tier scale. Light browsing at worst; rarely ruined.
- What hardiness zones does Trillium grow in?
- Trillium is hardy in USDA zones 4 to 8. Outside that range it will either not survive winter or will struggle with summer heat. That is the range across the genus, so a named species or cultivar may be narrower.
- Does Trillium grow in shade?
- Yes. Trillium tolerates full shade to part shade, which makes it one of the options for a shaded bed where deer also browse.
