I have two fruits on my P. caerulea. I would like to keep them for seeds but don't know anything about passiflora seeds. I've searched but didn't come up with much information. I'm wondering when do I pick the fruit. How to dry the seeds and how long are they viable?
Let them fruits fall naturally--don't pick em. You can put them in mesh bags that you tie to your trellis--that way you don't have trouble finding them when they drop. I have read that the seed embryos continue to develop after the fruit falls (they get nutrients from the juice in the arils), so you are supposed to let fruit ripen at least a week or two before removing the seeds. I have successfully germinated incarnata seeds that were left in the fruit for 4 months before being removed, so I don't think it really matters how long you leave them in the fruit. The seeds should be good for several years, but germination rates decline over time. Some say that fresh wet seed germinates best, but I have not found this to be the case with incarnata or Incense x caerulea. Good luck!
Wonderful, thanks for the information. I look at my passi everyday so I shouldn't miss the fruit falling. Most of the seeds will be used in the same spot so I will let one of them go naturally and see what happens. I'm trying to fill a large area where an oak fell, they are growing up the roots of the fallen oak now.
I was reading up on your crossing efforts. Do you sell the hybirds or is it just a personal hobby? I'm not far and neither is jlp222 (another local that loves passis).
Its just a hobby, and I'm really just a beginner. Last year was my first year growing anything other than caerulea and incarnata. I was able to get about 15 fruits on my Incense--all crossed with caerulea. The fruits had a lot of flat seeds, but I did get about 200 that looked viable. I planted 30 earlier this spring, and only 6 came up. Of those, 2 died, 2 are weak, and 2 were vigorous. So I planted another 70 seeds a week ago. The first one popped out today. I am hoping to get something that looks like Indigo Dreams. I have some extra Incense seeds--if you want some just send me a few stamps. Plenty of incarnata also.
I'm trying to germinate some kermisina and loefgreni seeds now. So far nothing. If they don't start to get with program soon, I'm gonna have break down and buy them as plants.
