which break into masses of whitish flowers. Showy reddish 
pea-sized fruit on long stems in fall. Dense spreading growth.

Malus hopa, REDFLOWERING CRAB 12'

flowers and small fruit which is red inside and out. 
4-5 foot $1.50 
Malus ioensis plena, BECHTEL CRAB 12'

a ragged appearance. 3-4 foot $1.75, 2-3 foot $1.25 
Malus niedzwetzkyana, RED-VEIN CRAB 15' 
Attractive red flowers, fruit, leaves and wood. 4-5 foot $1.50

a very large tree. Brown bark scaling off in places exposing 
smooth greenish-white bark. 4-5 foot $1.00 
Populus alba bolleana, BOLLEANA POPLAR 80' 
The best of the slender columnar type of poplar. Has smooth 
green bark and leaves which are white on the underside. 
The poplars are all quick growing short lived trees. They are 
shallow rooted and require a great lot of water, and are also 
subject to disease and insect pests. They are rank feeders 
robbing the surrounding soil of water and food for a great 
distance. These are effective for tall background hedges 
or to emphasize vertical lines. 
2-3 inch $4.00, 1-2 inch $3.50, 8-10 foot $3.00, 0-8 foot $2.00 
Populus nigra italica, LOMBARDY POPLAR 60'

and bark similar to the Cottonwood. Was planted in old 
Italian gardens. 6-8 foot $1.25

rado. Slow growing and long lived. 3-4 foot $1.25

A cross between the Chinese and American elm — Leaves and 
branchlets like the American, but habit of growth more like 
the Chinese. Very rapid growing. A new thing but it seems 
to have great possibilities. 
2-3 inch $3.00, 1%-2 inch $2.00, 1-1% inch $1.50, 6-8 foot $1.00
