Persimmons in Colorado?
HI, has anyone grown American Persimmons in Colorado? I have seeds started and will keep them in the greenhouse for the first two years.
Also, has anybody successfully grown Jujube in Colorado. I am located on the front range just east of Denver.
Arapahoe County Colorado
Persimmon is not a fruit grown in Colorado, so little research can be found about the success. Below is a link to a paper from the New Mexico State University about types, varieties, cold hardiness, and concerns of growing persimmon in colder climates. Overall, this paper notes that persimmon is best suited to warmer climates.
Native persimmons are a little more cold hardy than the Oriental varieties, but would still perform better in USDA Hardiness Zones 7 to 10. (Arapahoe County USDA Hardiness Zones are 5a&b.) The trees prefer moderate winters, of which Colorado is not. The trees can break dormancy during warm spells in spring, only to be hit by the late freezes in April & May, the trees do not perform well in high summer heat void of humidity, and early autumn freezes can affect the fruit that is ripening. Finally, persimmons grow best in deep, well-drained soil, which might be difficult to find in Arapahoe County.
Jujubes (aka Chinese dates) in Colorado are much like persimmon. Jujube has a borderline cold tolerance of Zone 6 and needs a long growing season for the fruit to ripen. See the information provided from New Mexico State University above.
If you are interested in growing fruit, there is a better chance of success in planting fruit trees that are best suited for the Front Range:
