Other Rhododendrons 
R. hirsutum and R. ferrugineum. Two fine hardy European species (not 
hybrids) of compact growth and masses of small bright pink flowers. 
Of great value for the rock-garden and for planting with other Rhodo- 
dendrons. They differ but little in general appearance, but the leaves 
and twigs of hirsutum are quite hairy. 
R. arbutifolium {mtsonianum) . This hybrid between punclatum and 
H. ferrugineum is one of the very best hardy sorts. Amass of pink 
fragrant flowers in July. 
The hardial Hybrid Rhododendrons, growing at Salem Branch Nursery 
Kalmias 
Kalmia latifolia. The Mountain Laurel. One of the grandest of our 
native broad-leaved evergreen shrubs, attaining tree-like proportions 
in our southern mountains. In cultivation it is a broad, thick shrub, 
and, when in full bloom, of surpassing beauty. The wheel-shaped 
flowers are set in close corymbs on the ends of the stems, pure white 
to pink and appear in May or June in such profusion as almost to 
smother the foliage. Its thick, shiny leaves are conspicuous the year 
round, making it a shrub of greatest value for massing and giving a 
striking evergreen effect. The hardiness of Kalmia latifolia is beyond 
doubt, it being found sparingly in Nova Scotia and increasing in 
abundance through New England and the middle Atlantic states (par- 
ticularly in the higher altitudes), till the crest of the southern Alle- 
ghanies is reached, wherein, the true American home of the broad- 
leaved Ericaceae, perfect conditions of soil and climate are found,
