Oriental Flowering Trees and Shrubs 
At the United States Plant Introduction Garden, Chico, Calif., however, 
moderate crops are home practically every year hy the single forms, and at 
the Arnold Arboretum, Jamaica Plain, NIass., nearly all of the single¬ 
flowering cherries bear good crops of seeds annually. Unusually late frosts 
sometimes injure the flowers o f the Yosh ino (Prunus yedcensis) at the 
Arboretum, and the results are a very light crop. Further tests with the 
flowering cherries will no doubt indicate other regions favorable to seed 
production.’ 
Soil AND Moisture^ — In any reasonably good, well-drained soil, with 
average moistures, these cherries should thrive. In general, the same soil 
conditions should obtain under which the fruiting types of cherries do best. 
Planting, Pruning, and General CARE^“The double-flowering cherries 
are seen to best advantage when planted singly or in small groups against 
a dark background, either of evergreens or of small structure which har¬ 
monizes in color with the flow¬ 
ers, The single-flowering forms 
also show up well under simi¬ 
lar situations, although they 
are more suitable than the 
double varieties for planting 
along parkways and avenues. 
Care must be taken to allow 
enough room between the trees, 
especially those of spreading 
habit; forty feet apart woidd 
be a good general planting 
practice, (My opinion is that 
20 to 25 feet is a very liberal 
distance under usual condi¬ 
tions. A. E. Wohlert.) Further¬ 
more, the trees require plenty 
of sunlight for best develop¬ 
ment. Since they are grown 
primarily for the sake of the 
flowers, pruning the trees is 
not advisable, except to remove 
dead wood or to correct some 
undesirable tendency in habit. 
Cultivation and fertilizing are helpful, especially with young trees, and shoidd 
be carried on in the same general way as wi th th e cherries o f fruit ing types. 
Diseases and Pests^ —In general, the flowering cherries are subject to 
the same diseases and pests as other rosaceous woody plants, and similar
