Are you sure that "apple" gourd is a luffa, and not a bottle gourd (Lagenaria siceraria)? There is an 'apple' type on the AG2T website, in the bottle gourd section.On the luffa thing: that's sort of what I am hoping as well; that I can de-hybridize the apple luffa and get an OP that retains the short, fat fruit shape (you'd think that there would have to already BE one to make the cross in the first place, but if there is, I have never seen it.)
Summer Treasure, which is reddish-brown & white. That is a color scheme I seek, since I have 4 of such varieties (3 from the Philippines) and they are all very good. I'm holding my breath on the white-seeded one, since I tried one of those before that proved to be short-day only... lots of leaves, and only a few flowers just before frost.Which other one is bi-color?
That was one of only 3 short-day yardlongs I've trialed thus far; fortunately most varieties seem to be day-neutral, regardless of their tropical origin.The importing part initially concerned me as well, since there are a lot of horror stories on the web about Chinese seeds being shipped illegally... so I sent them an email asking for clarification. They responded that they import seed via legal means through APHIS, and repackage it for U.S. sale. All of which was clearly posted on their website (which I had just glanced over - ooopsDid you read the "about?" Florida company distributing imported seeds.
(Do you suppose they accept PayPal?)
So it appears the seeds they are importing are the products of modern Chinese breeding, which IMO opens up a whole new world (almost literally) to those of us who grow Chinese vegetables. I hope this company sticks around, introduces us to more new varieties, and that at least some of those varieties prove to be adapted to places in higher latitudes than Florida. Time will tell.
I was just discussing this a few days ago with someone on another forum (this was the person that first referred me to the AG2T website). They were interested in growing their winged beans (as was I, after watching their videos). The poster had commented about winged beans suddenly disappearing on the AG2T website; I found them much as you did, listed in Chinese only. When I pointed this out, the poster contacted AG2T... they responded that they had received too many negative reviews about their winged beans from Northern growers, so had pulled down their English catalog listing. (No explanation as to why they were still listed in Chinese). 
That's not a plant, it's an obnoxious roommate! The photos of engulfed trees remind me of kudzu, so I hope you have a second floor - or an escape plan.
