PRUNUS. PJum. 



Under this heading are embraced some of the most charming early spring flowering shrubs. 

 Prunus tnloba or the Double-flowered Plum, as it is commonly called, and the Double-flowered 

 Almonds produce in remarkable profusion, perfectly double, finely formed flowers of most 

 attractive colors. At the blossoming season each little tree appears like one mass of bloom, 

 forming a most beautiful and interesting object, whether planted singly upon the lawn or in 

 groups. As the Almond and Plum flower at the same time, they can be massed very effec- 

 tively. Both are hardy and of fine habit.

 flowers in May. 50 cents.
