peaches perish more easily, but, like the magnolias, 
they give in a short life the worth of the money 
spent. The blood-leaved peach has excellent dark 
foliage. Another shrub in this group, A. sibirica, 
begins to bloom in late March or early April. 
Small trees of laburnum (Cytisus), which need 
alittle shelter; dogwood (Cornus florida), both 
the white and the rare pink; the Japan Judas tree 
(Cercis japonica), silver bell (Halesia tetraptera), 
witch hazel (Hamamelis japonica), cornelian 
cherry (Cornus mascula), double English haw- 
thorn (Crataegus oxyacantha) and white fringe 
(Chionanthus virginia) all make good garden 
shrubs. ‘Those that grow large develop slowly; 
but none of them should be planted without due 
allowance for future expansion, as transplanting 
is not so easy as with shrubs proper. 
What used to be called wallflower (Kerria jap- 
onica) in the old double form has a great deal 
of garden effectiveness in the species; the single 
yellow blossoms have a long season and the green 
branches are handsome. The white kerria 
(Rhodotypos kerrioides) is quite as good and it 
has black berries that last all winter. Other fine 
white-flowered shrubs, yet rarely seen, are the 
pearl bush (Exochorda grandiflora) and the dwarf 
Juneberry (Amelanchier botryapium). 
One of the unfortunate things about shrubs in

ple shades in the bloom. There are enough shrubs 
to supply it, but these colors do not seem to go with
