On the other hand, all the fine varieties sent out by Gill, Reuthe, Smith of 
Guernsey, and other nurserymen are, except with protection and very great care 
in selection of site, not even winter hardy. On the other hand the variety 
Kermesinum, which many good judges consider the best of all, makes its growth 
late, and seldom gets cut in spring, although it too is very winter tender. 
Personally, after succeeding with it for years, six good plants which I possessed 
are now destroyed. This should not, however, deter others who possess better 
and more sheltered gardens than mine from growing it with success. Up till now 
I have seen it well grown in my neighbourhood by Sir E. Loder, Mr. Charles Nix, 
and Colonel Stephenson Clarke. 
It will stand 20° of frost, but below that we must expect to lose it. The 
“ Tregothnan ” variety I find equally tender. 
Rh. arboreum var. Andersoni, good rosy-red flowers. Hardy. 
Rh. arboreum var. Blushing Beauty. A very fine variety raised by Gill, 
with large blush flowers. Hardy. 
Rh. arboreum var. Campbelli^. Flowers purplish-rose. Fairly hardy. 
Rh. arboreum var. carneum. Blush-pink flowers. Hardy. 
Rh. arboreum var. “ Mrs. Henry Shilson.” A very popular variety with 
handsome long foliage and large rather bluish-pink flowers. This variety is by 
no means hardy, and except under the best conditions difficult to grow. 
Rh. arboreum var. Nepalense. Bright red flowers, rather tender. 
Rh. arboreum var. nigrescens. Blackish-maroon flowers, tender. 
Rh. arboreum var. nilagericum. Flowers generally deep-rose, tender. 
Rh. arboreum var. ochraceum. Good pink flowers. Hardy. 
Rh. arboreum var. puniceum. Red or purplish-red flowers. Hardy. 
Rh. arboreum var. “ Sir Charles Lemon.” A very fine variety with very 
dark leaves with orange-brown pubescence beneath and flowers of the purest 
white. Certainly one of the best varieties we have and fairly hardy. 
Rh. arboreum var. Wearii. Perhaps the finest pink variety yet raised 
(Smith, of Penjerrick). Hardy. 
Rh. arboreum var. Windsori. Medium crimson flowers. Hardy. 
Rh. arboreum var. Zeyl.4Nicum. Rich pink flowers. Very tender and a 
slow grower. This and the next named will probably be regarded as new species. 
Rh. arboreum var. Kingianum. Brilliant crimson flowers. Very tender. 
The Chinese form of Rh. arboreum, namely, Rh. Delavayi, is also tender 
in the home counties. 
In this short note it is not my intention to discuss the innumerable hybrids 
that have been created between Rh. arboreum and other species and hybrids. 
The majority of these are now valueless, much better things have taken their 
places, but it is enough to mention three which have proved a real boon to 
British gardeners who live in cold places where moisture is always fitful. These 
three hybrids are “ essentials ” in every garden where rhododendrons can be 
grown.
