We're 2 miles from the beach. It rarely breaks 80, but we hit mid 80s several times this year. On 9/6 it hit 99.8. Unlike the thermometer, I haven't checked the humidistat accuracy, but it says mostly above 80, except for the occasional Santa Anas. The Mission Dolores gets some morning sun, since it is planted under the east dripline of a mandarin tree. I changed my mind on building a new arbor on that side, so I directed it west under the tree, on the north side, and then up the stake, so it's probably about 15' long, in mostly shade. I'm planning to run it along the string lights under the arbor, so it will remain shaded by the other vines on the top of the arbor.
The fruits fell off, but I also put a metal mesh bag on them, so there was some added weight. The mice and rats go after the passion fruit, so I didn't want to risk these. They're very light otherwise, so they may have hung longer on their own. Actually, do some passion fruit not drop, or get overripe if not picked? I've been waiting for the ligularis to drop, but perhaps I just need to pick them? This is one with its chain mail +2.
As for the taste, my wife's the real consumer. I'm just her dealer. I didn't find the first one very melon-y, but I just tried the second one, and it was very different. It was much sweeter, and melon-y, but it lost almost all of the floral aspect. I definitely want to compare future ones with the amount of maturity/aging, but I would so far prefer the fresher more floral version.
