Sweet Cherry: Lapins
Known for producing delicious, large sweet cherries, Lapins is hardy to zone 5, and is self-fertile, meaning you don't need another sweet cherry tree to get fruit.
Rootstock: Mazzard. Full-size, most popular cherry rootstock for centuries. Relatively tolerant of wet and heavy soils compared to other cherry rootstocks.
Fruit: Lapins is a heavy producer of large, dark cherries that ripen later than many other sweet cherries.
Uses: Fresh eating, and any other use you can think of - dried, juice, preserves, pies, and more.
Disease resistance: Not known for any particular susceptibility or resistance to disease, but is resistant to rain cracking.
Parentage: Van x Stella. Named after Latvian-Canadian cherry breeder Charles/Karlis Lapins, who developed self-fertile cherry cultivars at the Summerland Research Centre in BC. Summerland has been a centre of cherry breeding in Canada and is still the primary source of virus-free propagation material for fruit trees in Canada.
Pollination: Self-pollinating, and an excellent pollenizer for other sweet cherries.
