Identifying Passiflora varieties
Back in the spring I purchased three types of Passiflora seeds: incarnata, caerula and alata. Though I had 5, 15 and 8 seeds respectively, I only ended up with 1, 2 and 2 sprouting. Problem is... the leaves on the 'alata' do not look like the leaves I see in pictures on the web. All five vines are growing nice and healthy, but only the incarnata has yet to produce flowers, which is fine since I had read that it can take 1-2 years before you see blooms on seed-started vines... if at all. So I'm left wondering if there's any other way for me to find out just what my mystery third Passiflora is? I know that leaves can at least rule some types out, but is there a way to really narrow it down without seeing a bloom?
I'm including a couple pictures of this mystery Passiflora. In both pictures you can see the lobed, but not-quite-as-lobed-as-incarnata nature of the leaves and in the first picture you can see the fuzzy nature of of the vine stem, which does not appear on my incarnata vine.
