Maypop (Passiflora incarnata)
1 seedling plant. Not reliably hardy in zone 5!
These gorgeous vines are native to the south east, one of the hardier passion flowers they can survive into zone 5, although i have not found them to be reliably hardy. They are easy to grow in pots and can be overwintered in a unheated basement or root cellar in zone 5 or colder. Plant 2 or more if you want fruit which resembles it’s close relative, the passion fruit.
