each. White Flowering Almond, same price.

of the plants will produce black fruit, a few will have yellow or bright 
red cherries in racemose clusters. 75 cents each.

haps the dwarfest of oaks. It seldom exceeds three feet, and the small

differs in its dwarfer habit, its small red fruit clusters and very dark, 
glossy foliage. Foliage brilliant red in autumn. A shrub of exception¬

with aromatic trilobate foliage and brilliant red berries in showy termi¬ 
nal clusters. Best in a sunny, dry or well drained position. 75 cents

killing. Should be planted where their invading habit will not be ob¬ 
jectionable.

large rose-colored pea blossoms. Large, 75 cents.

custs. Flowering size, $1.00 each.
