I do. I knew Bob Muckle who hybridized it. I wasn't sure if it was well-known or not. It's a nice tree with very bright flowers compared to most plums. I don't have one but I know where one is... I don't even know if they're commercially available. Hopefully one of our tree guys can help you more.

Many nurseries have it in Canada,...I had to get one this year, not sure if the US have it.

I've got 10 coming in this year.

Growing it for a couple of years now and love it! It's a very good bee plant also.
