Glad I found this place!
I was mulling around my lilacs last week, when I noticed what seemed to be a snake growing straight out of the ground (ha ha). I left the plant in place to see what would come of it, and this is what I found this morning (see pic).
There's a flower in a long, deep cup shape, whitish with some purple and a fat, deep purple pistil (?) in the middle.
I'm near Montreal (5b).
