SHRUBS 121 



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 

 a little shelter; dogwood (Cornus florida), both 

 the white and the rare pink; the Japan Judas tree 

 (Certis 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 grandiftora) and the dwarf 

 Juneberry (Amelanchier botryapium). 



One of the unfortunate things about shrubs in 

 the North is the lack of true blue, violet and pur- 

 ple shades in the bloom. There are enough shrubs 

 to supply it, but these colors do not seem to go with
