We have a several Trillium plants in our yard and I am alway happy to see them bloom. They have a unique symbiotic relations ship with ants and sometimes mice, both of which are a common sight in the area. When the seeds in the ovary of the Trillium are mature, the plant secrets a scent that attracts the ants who carry the seeds to their nest and keep them safe in the ant garbage pile for germination. The Trillium is super sensitive to being disturbed and the recovery time from moving or picking the flower can take as long as seven years. Needless to say, the Trillium plants in the yard get to stay where they pop up.
I remember chaperoning a class of kindergartners on a field trip to a Wilderness Awareness field classroom and seeing the distress on one of the counselors faces when one of the kids triumphantly plucked the flower off a Trillium plant. The patient counselor then politely explained why that shouldn't be done. Luckily a lesson that was etched in my brain.
