I don't know dwarf flowering almonds (or Chinese plums), but these deeply serrated leaves are not what I'm seeing for Prunus glandulosa. What about Prunus triloba 'Multiplex', also a flowering almond?
Thanks wcutler. Darn it last time said Prunus triloba 'Multiplex' and it was Prunus glandulosa rosea plena. This time said Prunus glandulosa rosea plena. and it is Prunus triloba multiplex. Must concentrate. Back to school!
