CATALOG OF HIGHLANDS NURSERY 
RHODODENDRON CATAWBIENSE, continued 
Do not confuse this true species, which is absolutely hardy, with the 
common so-called catawbiense hybrid seedling so freely imported from 
Europe, which is at best half-hardy, and even when branched above is a 
single stem, showing bareness underneath for years. 
Unlike Rhododendron maximum, it is a very free bloomer, with foliage of 
a dark, rich, lasting green, which never rusts. The trusses are a bright 
red-purple (in marked contrast to the muddy purple of the semi-hardy half- 
breed imported variety noted above), and, as sent out by Highlands Nur¬ 
sery are always on their own roots. 
For massing to produce a broad-leaved evergreen landscape effect, there 
is no plant equal to it in the latitude of the Northern United States and 
Canada, where strictly hardy plants must be employed. As a rich, finished 
border to plantations of the commoner Rhododendron maximum and Kalmia 
lalifolia, the value of Rhododendron catawbiense cannot be overestimated. 
Do not compare our many-stemmed clumps with the single¬ 
stemmed, “bushy” half-hardy Rhododendrons offered by im¬ 
porters. There is 
comparison.

^Rhododendron maximum 
THE GREAT AMERICAN ROSEBAY 
Perfectly Hardy in the Latitude of Quebec 
Rhododendron maximum is, without doubt, the noblest of American 
broad-leaved shrubs. It is found growing sparingly in New England 
and New York, more abundantly in the Pennsylvania mountains, 
but reaching perfection only in the Southern Alleghany mountains 
where it grows in such luxuriance as to form a striking feature in 
the mountain landscape. Its large, waxy white or delicately pink 
flowers appear in large trusses in July, the latest of all the Rhodo¬ 
dendrons, greatly enhancing its ornamental value as a broad-leaved 
evergreen for finished landscape effect. 
Not even in Asia do Rhododendrons grow more luxuriantly than 
in our Southern Alleghany Mountains, where they attain a height 
of 30 feet or more. They must be seen in their native lavishness of 
growth and bloom, on the mountain-sides or hanging over the dash¬ 
ing ice-cold streams and water-falls, to be properly appreciated, 
and a trip to the high Carolina mountains in spring and early 
summer is a never-to-be-forgotten scries of joys to the lover of 
nature. 
In our northern gardens Rhododendron maximum (and other 
species to a small extent) is subject to damaging attacks from the 
lace-wing fly, particularly in sunny locations. We recommend an 
emulsion of five to ten pounds of whale-oil soap and one to two 
quurts of kerosene to 100 gallons of water, used with a spray pump 
having a fine nozzle. Per 10 100 1,000

*Rhododendron carolinianum (punctatum) 
The smallest Allcghanian species, though it often attains a height of 15 
foot and is wide-spreading. A very graceful shrub, with totally different 
nspcct from the two species preceding. Leaves dark green, usually blunt 
and narrow, covered with rusty dots below, much smaller than either maxi¬ 
mum or catawbiense. Flpwer-clusters appear in greatest profusion in 
June, covering the plant with a rose-colored mantle. Fine for rocky slopes 
or hillsides, standing exposure unusually well, and invaluable as a single 
specimen or for massing with the other species. 
Until this year we have been sending this beautiful and rare species out 
under the name of punctatum. Prof. Sargent has recently called attention 
to the fact that it is a distinct species from the punctatum. differing in 
time of bloom, with more showy and profuse flowers, and malung a much 
lnrger and finer plant than the punctatum.
