New to passifloras, a bunch of questions
Could somebody please explain the requirements for fertilizing the flowers? I'm confused on the non-self-fertile issue. I'm considering ordering 6-8 plants from Grassy Knoll. Do I need different types of plants, same exact flowers,completely different varieties or same types but different varieties to get fertilization? Some of the Grassy Knoll listings have the scientific names but not all. Can they all be cross-pollinated?
Do I need to buy at least two of each type in order to get fertilized fruit, unless I don't care?
Does p.incarta have decent fruit or are they insipid? Does the grenadilla tolerate heat? How about p. Jennifer grace, I love this flower but can't find any information about hot or cold tolerance.
I would love to have at least a couple of vines that produce good fruit, as I fell in love with passion fruit for fresh eating on a trip to Africa. Don't even mind the seeds. I prefer the purple fruit.
Any recommended varieties for zone 9b low desert? I have partial or bright shade areas, full sun areas but there's nothing I can do about the sometimes nearly 120 degrees dry heat that we get with high nighttime temps in July and August. I do have irrigation and can also water by hand as needed. I know a lot of people grow Frederick, although it does get frozen sometimes when we have severe freezes.
I will plant in-ground those plants suited for my zone and keep in pots the more tender varieties so that I can cover or bring them indoors as needed.
How big of pot do I need? How do you move vines, do you cut them back at the end of the season?
Are any of the vines considered invasive in a desert environment? With every two weeks irrigation? If so, I'll probably pot all of them.
Finally, are there any varieties particularly attractive to hummingbirds? I'm trying to make a sort of hummingbird oasis.
Do all passiflowers bloom at the same time? Or can I plant some that bloom at different times?
How do they do with organic fertilizers?
I have a large concrete wall that I intend to put wires on for trellising, is this okay? I'll probably add a couple of winter blooming vines for contrast, I assume with enough space and air flow that this is fine?
What pests bother passiflora besides caterpillars?
