History: Carmine Jewel is one of several dwarf sour cherry shrubs developed at the University of Saskatchewan in an effort to combine cold hardiness, dwarf stature, and good quality fruit into one variety. This effort was started by Dr. Kerr (for whom Kerr applecrabs were named) in the 1940s and Carmine Jewel was released in 1999. It is considered the hardiest of the cherries they developed. Carmine Jewel cherries are now the most commonly grown commercial cherries in the prairies.
Why We Grow It: Carmine Jewel is a notably productive cultivar with small cherries that have a high flesh-to-pit ratio. Thanks to their firm flesh, they are a preferred variety for freezing and drying. The shrub is on the smaller size, reaching 6-7ft once mature, great for anyone who loves cherries but doesn't have a lot of space!
Canadian Hardiness Zone: 3
Soil Preference: Sandy loam, loam, clay loam. Prefers average to moist conditions with well-drained soils, avoid planting anywhere that floods for more than two weeks in the spring.
Growth Habits and Disease Resistance: Moderately vigorous, compact growth habit and reaches about 6-7ft at maturity, good crops. Generally disease resistant.
Sun/Shade: Full sun (approx. 8-10 hours of sun daily)
Pollination: Self-pollinating, this variety will produce fruit without a cherry tree of a different variety but will produce more and better fruit if one is present. Sweet and Sour cherries cannot be relied upon to pollinate each other.
