Diospyros virginiana Prairie Sun® CLAYPOOL

Prairie Sun Persimmon (Diospyros virginiana Prairie Sun® CLAYPOOL) is a seedless, early-ripening American persimmon tree developed by the late James Claypool of Illinois. Claypool was a central figure in what is widely regarded as the world’s largest American persimmon breeding program and introduced several outstanding cultivars within this Prairie Series. Also known as Prairie Sun Claypool Persimmon, this variety produces abundant crops of orange-yellow fruit.

Persimmons are highly astringent when unripe due to naturally occurring tannins. As the fruit matures, Prairie Sun Persimmon becomes deliciously sweet while remaining firmer than many other cultivars in the series. Persimmons are often described as candy-like, with a rich, complex, date-like flavour. When fully ripe, the fruit is highly nutritious, offering abundant antioxidants, dietary fibre, and vitamin A. Excellent for fresh eating, Prairie Sun Persimmon is also well suited for drying, syrups, puddings, baking, preserves, and traditional persimmon pie. Birds, squirrels, and other wildlife are attracted to the fruit, so timely harvesting is recommended.

American persimmon tree (Diospyros virginiana) is native from Connecticut to Kansas, and south to Florida and Texas. While its fruit is smaller than that of Asian persimmons, American persimmons are significantly more cold-hardy. Prairie Sun Claypool Persimmon is a reliable producer in cooler regions and is hardy to zone 5 (–29 °C), with harvest typically beginning in October.

Beyond its fruit, American persimmon trees are prized for their ornamental value. Diospyros virginiana is a deciduous tree with an upright habit and a rounded to oval crown, capable of reaching up to 18 m (60 ft) in height. Prairie Sun American Persimmon is more compact, generally growing just over 6 m, and can be maintained at 3–4 m with regular pruning. The bark is especially distinctive—dark gray to nearly black, deeply furrowed, and broken into blocky plates resembling alligator skin—making the tree easy to recognize in winter.

Leaves are ovate to elliptical, measuring 5–15 cm, and are glossy dark green through summer, turning attractive shades of yellow and red in autumn before dropping. Small (approximately 1 cm), fragrant, pale yellow flowers bloom in June and attract pollinators. Diospyros virginiana Prairie Sun® CLAYPOOL is self-fertile.

This self-fertile persimmon prefers full sun and grows best in moist, well-drained soils, though it tolerates drier conditions once established. No serious insect or disease problems are known. Trees typically begin fruiting within 2–3 years. If fruit does not fully ripen on the tree before frost, it can be further matured in cold storage; temperatures should remain above 4 °C to prevent deterioration of fruit texture.

Patience is essential—persimmons are among the last trees to break dormancy in spring. Watering while dormant will not hasten growth and may even be detrimental. During cool springs, trees may take longer than expected to leaf out; they simply require additional warmth to awaken.
