Has anyon had any luck with flowering and fruiting Passifloras indoors? I live up north (zone 4) but have a really sunny window, and could put plants outdoors in the summer.
flowering/fruiting passifloras indoors?
Yes, they will bloom if given enough light. They won't fruit unless the flowers are pollinated - do you have insects in your house? If no pollinators are available, don't expect fruit/seeds.
Unfortunately I do have insects in the house (cluster flies and ladybugs), but I guess I could always use a paint brush!
Are there any varieties that are especially good for growing in pots?
There are many passiflora that grow very fast that perhaps would not be good indoors however there are sellers that will put you onto a good houseplant like this one here;
Quickly in the descriptions of plants I found these;
