Sitka cherry

Anyone heard of “Sitka cherry”?

Raintree Nursery will be offering them this 2015-16 bareroot season. I will definitely be buying one just out of curiosity; I’m wondering if anyone has grown them?

Here’s Raintree’s description:
“A tart cherry grown in SE Alaska and reportedly brought from Siberia. It is the best producing cherry in their cool wet climate.”

If the description was changed from “cool wet climate” to “hot humid summer with low soil moisture” and had an added promise of great taste, I might be tempted. As it is, I consider that description code to Southeasterners for saying, “Move along. There’s nothing to see here, folks.”.
