16 MASS. EXPERIMENT STATION BULLETIN 345 



April or May crop of reddish-scarlet flowers, which together with Forsythia 

 light up a dull, early spring landscape. Best in full sun. There are numerous 

 cultivated varieties based on flower color, ranging from whitish through pink 

 to red. 



Chamaecyparis obtusa var. gracilis SLENDER HlNOKI CYPRESS 



A small, slow-growing, upright, evergreen tree of compact habit. Its dark 

 foliage is arranged in hanging branchlets giving the plant that aspect popularly 

 designated as "Japanese." Of limited usefulness, but worth mentioning be- 

 cause it is seemingly of greater hardiness than the type. 



CHAMAECYPARIS OBTUSA var. NANA Dwarf Hinoki Cypress 



A slow-growing, contorted-branched, rounded, evergreen plant suitable for 

 large rockeries, or as a substitute for Boxwood in certain situations. 



CHAMAECYPARIS OBTUSA var. PYGMAEA Pigmy Hinoki Cypress 

 Because of extremely slow growth and low, horizontal, spreading habit, 

 this evergreen plant would seem to have a place in the rockery or, in certain 

 situations, in masses as a ground cover. 



Chamaecyparis pisifera SaWARA CYPRESS 



A tall-growing (one hundred feet at full maturity), loose-branched, ever- 

 green tree which in the past has sometimes been forced into garden use as an 

 inappropriate substitute for Thuja occidentalis. It probably has little garden 

 value except as a large, open specimen with loose, horizontal branching and 

 shaggy, reddish trunk. 



Chamaecyparis pisifera var. filifera THREAD CYPRESS 



Rather pleasing as a small plant but, like the type, becoming tall and ragged 

 when older. There are a number of forms, probably the best of which is a 

 dwarf plant of bushy habit (sub. var. NANA) which remains compact and carries 

 on indefinitely the pleasing, thread-like appearance. 



Chamaecyparis pisifera var. plumosa PLUME CYPRESS 



A fine-leaved form usually seen in cultivation as a multiple-stemmed plant 

 which soon becomes open and ragged unless subjected to severe clipping. It 

 should not be used in limited areas, as has been the recent custom. When 

 given room enough and kept to a single leader, it will make a large tree of the 

 same open habit as the type. There are in cultivation a number of high- 

 colored but rather banal forms of this variety. 



Chamaedaphne calyculata LEATHERLEAF 



A somewhat ragged, spreading, broad-leaved, evergreen shrub which has 

 white but not too showy flowers in midspring. It is useful as a ground cover 

 for fairly moist, sandy or peaty soils, especially if cut back to ground level 

 every few years to insure dense, multiple branching. 



Chaste-Tree — See Vitex 



Cherry — See Prunus 



Chiogenes hispidula CREEPING SNOWBERRY 



A tiny, prostrate, spreading, broad-leaved, evergreen shrub with aromatic 

 foliage and summer-borne white berries. Notoriously difficult in cultivation, 

 it can be used only as limited ground cover or a rock-garden plant in moist, 

 shady, acid locations.
