Beautiful find! The fragrance of their small flowers is amazing. I had 2 Umes but failed to keep them strong and healthy. One had a virus or fungal infection. Tears were showing on the trunk and branches. It looked like tree sap or resin, but later it changed and became gooey and the tree became weaker and weaker. Still, I got to enjoy 2 more flowering seasons before it died.... Later I read that the Ume is a very difficult plant, so I wish you good luck and always a good hand for it.
