Prolific Pawpaw (Asimina triloba 'Prolific') is a heavy-bearing, American heirloom variety known for having fruit with a smooth, sweet, custardy texture and a classic tropical flavour, with coconut overtones. The tree grows vigorously, forms a tidy upright shape, and begins fruiting young.
In south coastal B.C. (Zone 8a), it typically ripens from late September to early October, around the same time as Shenandoah.
WHAT ARE PAWPAW TREES?
Pawpaws are highly prized fruit trees. Often called a “tropical fruit for the north,” pawpaws produce clusters of large, nutritious fruit 3–6 inches long with a custard-like texture and a flavour that’s been compared to mango, banana, pineapple, and even vanilla custard.
Unlike most tropical relatives in the custard apple family, pawpaws are uniquely cold-hardy (-25ºC), thriving in Zones 5–8 and capable of handling Canadian winters in many regions. Pawpaws are native to North American, including areas as far north as southern Ontario.
In nature, young pawpaw trees grow in the dappled shade of forest understories, gradually reaching into more sunlight as they mature. To mimic this, it’s best to provide shade for the tree's first 1-2 years—whether by planting behind a fence, under light tree cover, or using a temporary shade screen.
Most pawpaws require cross-pollination with a different pawpaw cultivar, or a seed-grown pawpaw. Seed-grown pawpaws are all genetically unique, so you can have two seedlings pollinate each other, or one seedling and one cultivar, or two cultivars. Named cultivars are grafted and selected for their exceptional fruit quality and yield. With seed-grown pawpaws, fruit quality can vary widely.
With an ever-expanding, cult-like following, pawpaws reward growers with one of the rarest and most delicious fruits you can grow in a northern garden.
