Cautiously consider passionfruit like the tropical lilikoi or maypop that is native to north America. Chinese magnilia vine is another great option. I do strongly suggest that they be isolated if you plant them where they will be perenial by either using a large pot and dripper or having an unirrigated grass or dry pathway bordering them. Using a tropical non perennial and bringing a couple specimen inside for the winter is probably the safest bet to be safest from them becoming invasive. Chinese magnilia vine is very invasive and hardy so use extreme caution when planning it's location. These plants are very desireable and well worth the efforts to try growing them. Passionfruit is extremely flavorful and sour if you enjoy such flavors. I am currently growing them as a hanging basket in my window. Chinese magnilia is called five flavor because it is sweet, tart, salty, bitter, and delicious. It is extremely nutritious and one of the esential Chinese medical herbs.
