I am not sure if your tree is a Santa Rosa. Where did you rescue it from? Home Depot? If so, chance of mislabeled tree is good.

plum takes about 3-5 years to fruit. Your tree is too young. Luckily, it may have some blooms next year. If not, by year 4, it should.

However, Santa Rosa is not as hardy as Shiro. Flower buds can get killed in your zone or when late frost hits.

even if it is a real Santa Rosa, it is iffy in your zone.

I kept the tag and it clearly is marked Santa Rosa and grows for zones 5-9. I have saw several other nurseries offer this plum making me believe it is okay to grow in my zone. I purchased it from Zehr's which is a large Canadian grocery chain (Loblaws) and it did indicate it is self-fertile but there is so much information on the web that it makes it hard to know if it is or if I should be buying a pollinator.

We had a VERY long and cold winter last year and it survived, leafed out and is doing well couldn't say the same for a mulberry and currant that didn't make it. I have had no blooms but again suspect it is due to being too young. If it doesn't need a pollinator as indicated then I will let it continue to grow and hope in a few years I get some plums.

Thanks for the info!

The others are correct, Santa Rosa is a warm weather plum, and will not do well in your area. Don't believe all of those nursery tags. They just want to sell product, and have very little knowledge about the variety.

Nurseries sell plants/ trees that they think people in general recognize and want to buy. Bing cherry is very well known. It can grow well in only certain areas but they sell this tree anywhere all over the country.

those who like persimmon, have heard about Fuyu. They sell Fuyu here in zone 5/6 while the tree is for zone 7 or higher.

like Rayrose said, they selling it does not mean it is suitable for your zone. Your tree may survive, your chance to get fruit is low.

While maybe not the optimum plum for zone 5, I bet you get flowers next spring, and a lot of flowers the following year; so I wouldn't take it out yet. Supposedly self fertile but another pollinator supposedly increases yields.

Sarah,

Santa Rosa is a goog plum. Hope you have mild winter. Please let us know next spring if it blooms and if the fruit set. A young plum tree may abort its fruit in its first year of bloom.
