"You Are Infected!"
This very attractive Trillium is infected with a plant disease.
I was excited to see this White-flowered Trillium (Large-flowered Trillium) in Northport, Michigan. I thought it was different species, or variety. Janet (jlst2i) thought it was bacterial disease. Janet was correct.
Phytoplasm (aka Mycoplasma-like bacteria) infects Trillium, and the result is the green stripes in the petals. This is an early symptom. Trillium being a perennial flower, the disease progresses each year until the petals are nearly totally green.
