I can't answer your question, but since you're in NoVA, do you know there's a place that sells passion fruit vines (the fruiting kind) in Arlington/Crystal City? It's called Nature By Design and it's tucked away on some weird little dead end street near National Airport. I bought a few plants from them a couple years ago and they are going strong now. One word of warning - - - the original plants send up new shoots EVERYWHERE. All season long I pull up volunteers from near and far away from the original plants.

heaven- do you have the ability to take your plants outside for a month or so during the fall to get chill hours. if yes, i would strongly recommend a mauritius lychee plant (my fave fruit). if limited strictly to non chill plants, u may want to consider jaboticaba- a delicious grape like fruit, that i am growing. my warm weather collection includes guava, lychee, jaboticaba, fairchild mango, 3 diff lychees, and 5 citrus. do you have any pics of your plant set up- would love to see. you should def post this question on the tropical fruit forum- you will get a much better response.

Wiley, I have plenty of little sprouts coming up from my lavender-flowered passiflora incarnata and would be happy to share a few bare-root shoots if I can find any more this late in the season (I just finished pulling & discarding a bunch, as I already have 4 potted and rooted for an upcoming local plant swap.) My plant was a gift sent bare-root from a fellow gardener in the southeastern U.S., where these plants are native, up to Virginia and southeastern Pennsylvania. It is perfectly winter-hardy without protection other than the usual winter mulch of shredded leaves in my USDA Zone 7 garden on the mid-NJ coast. Don't despair if you don't see anything in spring - these didn't earn their name "Maypop" for nothing! Due to our cooler spring this year, mine was up quite late, but has made up for it. I don't know how well it would fare through a zone 6 winter, but it wouldn't hurt to try. I would recommend planting it in a large, deep nursery pot sunk into the ground, as once established they do send up shoots quite a distance from the mother plant. Let me know if you are still interested - there should still be time for it to establish some roots before the soil cools.

I don't really care about the citrus, if it kills it oh well. I only actually use a few of the lemons a season anyway. I think I could prune the passion fruit back to keep it under control. In my zone it will die to the ground every winter as well. I am not sure how o root them yet. I have heard that they are easy, but I need to red about it more. For figs that I would be willing to trade I have: LSU Gold, Panachee, Barnisotte, Col De dam, Negronne, and Celeste.
