I got this seed in a trade, and Winter-Sowed it, but have been unable to find any information on it. The seeds were relatively large- looked like dried up petals, actually- papery and white with a pink edge.

Does anyone know exactly what this might be, and information for it? Googling pink globeflower nets me little except a pink primrose thing, but nothing that looks really like a globeflower (as I am familiar with, anyway...thinking of a trollius).

Thoughts?
