WOODY PLANTS FOR NEW ENGLAND 55 



yellow; "Bijou de Gandbruges", double pink; and "Raphael de Smet", double 



rose. 



RHODODENDRON INDICUM var. BALSAM INAEFLORUM BALSAM AzALEA 



A spreading, almost evergreen plant of extremely slow growth, for sheltered 

 rock-garden situations. Small leaves and double salmon-red flowers in June 

 or early July. 



RHODODENDRON JAPONICUM Japanese Azalea 



A much-branched deciduous shrub to some six feet. Like R. calendulaceum, 

 its seedlings, without hybridization, display individual flower color variations 

 ranging from yellow to red or salmon-rose, late in May along with R. roseum. 

 It endures less acidity than some other species. Vegetative propagation of 

 outstandingly distinct individual clons would extend to inland New England 

 a group of high-colored, large-flowered Azaleas with the garden value of the 

 more tender Mollis hybrids. One such clon is var. AUREUM which is a fine 

 yellow. 



X Rhododendron Kosterianum, "Miss Louisa Hunnewell" 



An Azalea, the type of which was a rich, orange-yellow flowered, hardy 

 hybrid between R. japonicum and R. molle. True plants of such a hybrid are 

 those propagated vegetatively from portions of the original stock which, in 

 this instance, may not now be in existence. Unfortunately, the material now 

 offered is of seedling origin and may often contain varying R. japonicum and 

 R. molle seedlings.

Rhododendron lapponicum LAPLAND RHODODENDRON 



A plant from Arctic tundra and mountain tops farther south, this species 

 is something for the understanding care of the enthusiastic rock gardener. A 

 one-foot shrub with tiny purplish flowers, it probably needs a cool, moist, acid 

 root-run and some shade. 



RHODODENDRON MAXIMUM RoSEBAY RHODODENDRON 



The well-known, tall-growing (seldom above fifteen feet in the North), 

 large-leaved, native species which in mass planting is most capable of giving 

 fine screen and evergreen mass effects. Its sparsely borne, whitish inflorescence, 

 which does not open much before July, is relatively small, and often hidden 

 by new growth. Wild, single-stemmed plants are usually open in habit and 

 straggly. 



Rhododendron minus PlEDMONT RHODODENDRON 



Belying its name, this species is loose and straggling, often growing to a 

 height of ten feet or more. Because of its hardiness, it is valuable for wood- 

 land planting where the magenta color of its late June flowers will not seem 

 unpleasant. Out of flower, it has the appearance of a coarse form of R. carol- 

 inianum. 



RHODODENDRON MUCRONULATUM 



The type of this tall, gaunt, deciduous shrub differs from that of the some- 

 what evergreen R. dauricum in having larger, brighter flowers, larger leaves, 

 and in being somewhat earlier in its blooming time in late March or early April. 

 However, in cultivation the two species seem to be mixed together and almost 

 impossible of separation. Planted in wood-edges or in large mixed groupings, 

 it can be made to light up the otherwise cheerless post-winter landscape with
