Wandering in the woods through masses of white trillium (T. grandiflorum) at peak flowering is a privilege.Trillium grandiflorumAn even greater and exciting treat is finding its pink form – Trillium grandiflorum f. roseum and interesting green variants. The pink flower form can be usually found mixed in large populations of ‘normal’ white trilliums. Scouting for them has to be done early because later almost all of the “whites” will also turn slightly pink when fading.

The greening of the White Trillium flowers is believed to be caused by infection with a pathogen belonging to the genus Phytoplasma. Phytoplasmic infections are usually confined to phloem and often result in the transformation of floral parts to leafy green structures, potentially leading to sterility of the plant. But there is more research to be done until all will be clear regarding this subject.

Trillium grandiflorum – green variant No. 2; I think ‘Green Feather’ would be a good name for it…

Trillium grandiflorum – the No.3 green variant, arising from a carpet of wild-ginger leaves

I can only watch closely my variants to see how they evolve and if they’ll form fruits/seeds. There is something beautiful about their ‘infection’ ;) At least the No.3 looks very happy and thriving.
