Trillium Festival

Welcome back Spring! The Annual Trillium Festival at Tryon Creek State Natural Area is an educational event for the whole community that celebrates the season of renewal in the forest and beyond.

This popular spring event looks a bit different this year, with the construction of the new education pavilion underway this year’s event will take place over two days.  Starting with a special donor appreciation social and plant sale on Friday evening, followed by a public event and plant sale on Saturday. 

Current members will receive an email to RSVP via online.

For 45 years, Friends of Tryon Creek has celebrated the return of the Trillium, an early-season perennial native to our local forests. This beautiful white flower awakens each year in late February and early March, and slowly turns to a reddish-purple by the end of April or early May, making it a wonderful beginning to the spring wildflower season.
