Prairie‑Perfect Cherries: Meet Prunus × kerrasis

🍒 Prairie‑Perfect Cherries: Meet Prunus × kerrasis

If you’ve ever dreamed of growing cherries in Manitoba but worried about winter kill, poor yields, or fussy trees — Prunus × kerrasis is your answer.

These dwarf sour cherries, bred by the University of Saskatchewan, are cold‑hardy, compact, and bursting with flavour. They’re part of the Romance Series, a group of cultivars that combine beauty, productivity, and resilience.


🌿 What Is Prunus × kerrasis?

This hybrid is a cross between Prunus cerasus (European sour cherry) and Prunus fruticosa (a hardy dwarf cherry). The result? A shrub‑like cherry tree that:

  • Survives −45°C winters

  • Produces large, sweet‑tart fruit

  • Grows just 6–8 feet tall

  • Is self‑pollinating

  • Begins fruiting in 3–4 years

It’s ideal for small yards, edible landscapes, and even commercial orchards.
