Can you suggest a passiflora?

funnthsun z7A - Southern VAApril 21, 2013

I am looking for a passiflora to put on a trellis and would love some suggestions, as I am completely overwhelmed with the search results that I have found so far. Here is what I WANT (I know one doesn't always get what one wants:)

1) A passiflora that doesn't spread by runners or become invasive (relatively easy to control). Not a monster in size, either. The trellis is only so big and don't want it reaching to other trellises, either, unless it's easy to control if it does.

2) White petal with preferred blue corollas, but can be dark purple. No pink anywhere! Petals can have a green tinge, that's fine.

3) Hardy in Zone 7

4) Long-bloomer

Well, there is my wants, so can you think of one that meets all or most of these wishes? Thanks for your help!

I'm not sure if such a plant exists. The problem is that plants hardy to zone 7 (and there aren't many) survive precisely because their deep roots survive the cold.

One possibility is Passiflora tucamanensis. However, I'm not sure if i will survive your zone. I've been meaning to ask a question about cold hardiness on the Passiflora Facebook group. If I do I'll see if I can include it, and report back here.

I'm pretty sure P. tucamanensis spreads underground to some extent. Whether it is aggressive is the important question. If it's modest, you will be happy to get some extras, as this is a hard-to-find variety, that others might be interested in trading for, or buying. I believe the best source is probably Jim Nevers, passiflorista on Ebay. Seeds from him may no be cheap, but they should be viable. He just posted in the Facebook group that he will be selling more seeds, but not plants.

A related possibility is P. 'Guglielmo Betto' (P. incarnata x P. tucumanensis). I've heard very positive things about the plant. Again, i don't know anything about its hardiness or whether it spreads aggressively.

Beyond that, I would just get a less hardy variety, grow it in a pot, and sink the pot into the ground every year. I'm sure people on this forum know ways to overwinter plants inside that requires a minimum amount of hassle. With that approach, almost anything is fair game. Look at a vendor's site, make up a list of your favorites, and then ask how big, how floriferous, etc.

One to consider; P. mooreana. Modest sized, and the flowers are reported to be intensely fragrant. Zone 10, think.

Probably the best site to look at is Grassy Knoll. I'll give a link to P. 'Guglielmo Betto'. I suspect she underestimates the hardiness, but I don't know for sure.

I suspect P. 'Guglielmo Betto', might come close to what you are looking for, probably spreading to some degree. The big question is hardiness. I've heard great things about that plant.

Here is a link that might be useful: P. 'Guglielmo Betto' at Grassy Knoll Exotic Plants
