If your not in an area that grows sweet cherries commercially sweet cherries are tough. Are you prepared to spray for brown rot? Are you prepared to put up scare tape or net your trees? If not your probably better off planting something else.
Under Eastern Conditions here are some cultivars you might try.
Blackgold self-fertile, very late bloomer which is good for late frosts but blooms too late to pollinate many other sweet cherries, crack resistant
Whitegold self-fertile, yellow with red blush, crack resistant
Black Tartarian great flavor, heirloom, brown rot resistant, once was commercially grown in New York when trees weren’t sprayed (1800s)
Other sweet cherries for Eastern conditions
Ebony Pearl, Burgundy Pearl- both are new and developed in the East
Emperor Francis- older yellow cherry
Also note most cherries are relatively soft. If you demand crisp,super firm cherries like Bing you are probably going to be disappointed.
Rootstocks
Semi-dwarf
Kymsk 5 and Gisela 12 are more resistant to canker than Gisela 6
Dwarf
Gisela 5
Full size
mazzard- default sweet cherry rootstock, large tree and slow to come in production, large tree means hard to net
For cherries it’s tough finding a cultivar on the rootstock you want.
For cultivars on Gisela 5 the only source is Raintree Nursery. For trees on Krymsk 5- Schlabach’s nursery and Trees of Antiquity. Cummins nursery sometimes carries trees on the Gisela series. I have seen them offer trees on Gisela 6 and 12. Trees on mazzard are easier to find.
I have Blackgold on Gisela 12. It bloomed the first year (I picked the blooms off). It grew little the first year but I bought a small caliper tree. The 2nd year decent growth. The 3rd year good growth. In the 3rd year, I got about 2 dozen cherries.
