and for window boxes or pots. As miniature trees they arc unequaled. The 
exquisite shadings of yellow, white and green, lasting all the year round in a group 
of this sort, are a constant source of pleasure; and these lovely colors arc particu¬ 
larly conspicuous and agreeable in the winter. 
R. ericoides. Heath-like Japan Cypress. (Ss) Regular, conical bush, 
desirable for contrast from its violet-red color in winter.
