Prunus x kerrasis 6-7' x same. Midsummer. U Saskatchewan intro, 1999.
Crosses between sour cherries and Mongolian cherries are causing a great deal of excitement in fruit-growing circles. Delicious blackish-red fruits with dark flesh and small pits are approximately the size of small sour cherries and ripen in early July. Good for both fresh eating and processing.
Some growers have reported getting 20-30 lbs per bush after 3-5 years. In our trials we saw fruit after only three years, and have found Carmine Jewel the best-suited cultivar for our climate.
Compact plant size keeps the fruit within reach and makes it far easier to net against birds than a standard cherry tree.
Prefers full sun and decent soil with a pH of about 6.5. Pamper them with mineral amendments and compost. Self-pollinating. Rare. Z3. Maine Grown. (1-3' bare-root plants)
