Re: Drosera brevifolia How can you tell Drosera brevifolia and Drosera capillaris apart? Do you know where I can get some Drosera brevifolia seeds too?
Drosera brevifolia is the smallest sundew species in the United States (~3cm). This species can be differentiated from Drosera capillaris by its wedge shaped leaves, and distinctly deeper red to reddish purple colour. The leaves of D. capillaris are circular and the folliage greener though you might have to have them side by side to tell! I found a key at: http://www.omnisterra.com/botany/cp/pictures/drosera/0077.htm#D.brevifolia which will give you a more scientific method of going at it, as long as you are up on your botanical lingo!
