hello all. I'm fairly new to passion fruit and trying to learn as much as possible , while also seeing conflicting info. I'm currently growing frederick variety. I'm interested in growing 2 more. I'm looking at sweet sunrise and panama red. I believe panama red can pollinate itself, but can sweet sunrise? I've read no and yes. I know a lot of yellow can not but read this one can, does anyone have more info? and if it can't can either the frederick or panama red pollinate it?
