PRUxVUS. Plum. 
Under this heading are embraced some of the most charming early spring flowering shrubs. 
Prunus tiiloba 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.
