So last year I collected seed from numerous D. rotundifolia and what was believed to be D. intermedia plants from my local bog.
This year the grown plants are flowering size. The D. rotundifolia is unmistakeable, but I have questions with the intermedia plants.
I have a couple plants that are identical to this, with white flowers: http://i114.photobucket.com/albums/n...stGiantF-1.jpg
I also have some plants that look identical to this: http://i114.photobucket.com/albums/n...eavedSunde.jpg
However, my version of the lower growing D. intermedia have just flowered PURPLE (rather than white)!! My question is this: Is there a purple flower form of D. intermedia?
