NC-1 Pawpaw (Asimina triloba) was selected in 1976 in Ontario, Canada for being early ripening, cold-hardy, robust and resilient.
In Blake Cothron's book, Pawpaws, in which he rates over 165 cultivars, he notes NC-1 is "one of the best varieties in general, but also has excellent potential in northern regions." He gives the cultivar an "A" rating overall.
The fruit flavour is described as very sweet, with excellent texture.
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 to -25ºC (-13ºF), thriving in Zones 5–8 and capable of handling Canadian winters in many regions. Pawpaws are native to eastern North American, including southern Ontario.
In nature, young pawpaw trees grow in the dappled shade of forest understories, gradually being exposed to increasing amounts of direct sunlight as they grow taller. Direct sunlight can injure young pawpaws, so it’s best to provide shade for the tree's first 2 years of life — whether by keeping it potted in the shade, planting behind a fence, in a large tree tube, or using a temporary shade screen. Trees purchased 5.5" band pots and 1-gallon pots will need one more year of shade. Plants in 2-gallon pots and larger will be old enough for full sun, assuming they started the year in full sun. Moving from shade to sun during the summer is not advisable.
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 is usually smaller and quality can vary widely.
With an ever-growing, cult-like following, pawpaws reward growers with one of the rarest, largest and most delicious fruits you can grow in a northern garden.
