Prunus cerasus 'Ulster'

Prunus cerasus ‘Ulster’ is a vigorous and hardy sour cherry tree, well-suited to Quebec's horticultural conditions, offering a generous production of dark red to black-red sour cherries with a tart, Morello-type flavor, perfect for pies, jams, juices, and preserves, while also being appealing for fresh consumption for those who enjoy tart fruits. This cultivar is distinguished by its vigorous, rounded habit, ideal for family orchards, large gardens, or productive plantings. Its white spring blossoms attract pollinators before the appearance of shiny green foliage, which adds an ornamental touch to the landscape. ‘Ulster’ is self-fertile, but the presence of a second compatible cherry tree can improve pollination and yield. It prefers full sun exposure and well-drained soil, neutral to slightly alkaline, and shows good tolerance to Quebec's harsh winters when planted in a protected zone 4b or zone 5.
