Plant Profile: Asimina triloba 'NC-1'

Asimina triloba, commonly referred to as pawpaw, is a small, deciduous tree native to North America, reaching heights of 20 to 30 feet. This species typically thrives in clusters within alluvial or other moist, nutrient-rich forests and can tolerate some shade in the understory; however, it requires full sunlight to produce fruit effectively. The tree flourishes best in well-drained, slightly acidic, and fertile soil. It is a slow-growing species, taking several years before it begins to bear fruit. The 'NC-1' cultivar, which hails from Canada, is particularly noted for its early-ripening fruit and a favorable pulp-to-seed ratio, resulting in a greater amount of edible flesh.

The leaves of the pawpaw are arranged alternately, emit a strong odor when crushed, and turn a vibrant yellow in the fall. Its bark is smooth and features wart-like lenticels. In the spring, the tree produces purplish-brown flowers with six petals. The fruit, which matures from late summer to early fall, measures between 2.5 to 6 inches in length and resembles a short, plump banana in both size and flavor, making it the largest fruit native to North America. To achieve cross-pollination, it is necessary to have multiple genetic strains.

Wildlife is particularly fond of the pawpaw fruit and often harvests it before humans have the chance.

Regarding diseases, insect pests, and other plant-related issues, the pawpaw tree is largely resilient, as it produces natural defensive compounds that deter most insect pests.
