History: Crimson Passion dwarf sour cherries are one of several dwarf sour cherries developed and released by the University of Saskatchewan with the goal of creating sour cherries that were cold hardy, shorter in stature, and produced good quality fruit. This initiative began in the 1940s and Crimson Passion was released as part of the Romance series in 2004. It is the sweetest of the Romance series cherries.
Why We Grow It: Crimson Passion produces large sweet fruit, excellent for fresh eating or processing. It contains the same sugar content (20-22 Brix) as sweet cherries, but also contains the tangy flavour of sour cherries, combining the best of both worlds into one cold-hardy shrub. This variety reaches up to 10' at maturity, great for anyone with limited space.
Canadian Hardiness Zone: 4
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, produces 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.
