My husband and I purchased an older home in Sacramento, Ca last fall. There is a deciduous tree that had green leaves before they dropped. To our surprise, in early spring the tree was inundated with beautiful pink blossoms about the size of a half dollar. When the leaves opened, they were a reddish plum color and curled before they flatten out. The tree is now shades of dark plum and moss green and has a fuzzy almond shape fruit or nut that is also plum and green in color. Does anyone know what this tree is? Thank you for any help.
