Hello, i am wondering to know how long this species live and the relation with productivity. Thanks a lot
Passiflora alata will live for many years. Productivity varies with the care you give it like any fruiting crop. If you fertilize it and prune it properly, and especially live in a place where it will be frost free, you can expect some good productivity. Certain cultivars may perform better than others, but I don't know any names.
