628 ARBORETUM AND FRUTICETUM. PARYT HI. 
as 20(t. according to other authors. It was 
introduced into British gardens in 1758, and 
produces its large and beautiful dark rose- 
coloured flowers in June, often continuing in 
tlower till October. 
Varieties. 
* R.h, 2ndna Dec. Prod.,ii. p. 262., is a plant 
hardly a foot high, which is a native of 
pine woods in Carolina. 
% R.h. 3 rosea Pursh has the leaflets, for 
the most part, alternate, and the branches 
smoothish. In its native habitats, on 
the high mountains of Virginia and Ca- 
rolina, it grows, according to Pursh, to 
a considerable shrub ; whereas the spe- ; 
cies is a low straggling plant. (4/. Amer, Sept., ii. p. 488.) 
% R.h. 4 macrophilla Dec., R. grandiflora Hort., figured in our Second 
Volume, has the leaflets large, and ovate-roundish; and the branches 
and peduncles glabrous, and without prickles. 
Description, &c. The species, and the different varieties, are shrubs, or low 
trees, with tortuous and very brittle branches; and leaves and flowers nearly 
twice the size of those of Robinia Pseud-Acacia. They form singularly 
ornamental shrubs tor gardens; but, as standards or bushes, they ean be only 
planted with safety in the most sheltered situations. A very good mode is, 
to train them against an espalier rail; and, on a lawn, this espalier may form 
some kind of regular or symmetrical figure: for example, the ground plan of 
of the espalier may be the letters S or X, or a cross, or a star; which last is, 
perhaps, the best form of all, the different radii of the star diminishing to a 
point at the top. Such a star, m order to produce an immediate effect, 
would require to have three plants placed close together in the centre, from 
which the branches should be trained outwards and upwards. R. hispida 
is often grafted about 1 ft. above the surface of the ground; and, when 
the plant is not trained to a wall, or to some kind of support, it is 
almost certain, after it has grown 2 or 3 years, to be broken over at the graft. 
A preferable mode, therefore, for dwarfs, is to graft them on the root, or 
under the surface of the soil. In purchasing plants, this ought always to be 
borne in mind. In consequence of the liability of this shrub to be injured by 
the weather, it is comparatively neglected in British gardens; but, wherever a 
magnificent display of fine flowers is an object, it better deserves a wall than 
many other species; and it is worthy of being associated there with Piptan- 
thus nepalénsis, Wistaria sinénsis, and other splendid Leguminacee. When 
grafted standard high, and trained to a wire parasol-like frame, supported on a 
rod, or post, 6 ft. or 8 ft. high, few plants are equal to it in point of brilliant 
display. At White Knights, there is a wall of some length covered with 
trellis- work, over which this species is tramed; and the flowers hanging down 
from the roof present a fine appearance ; though, as in the case of the covered 
walks of laburnum at White Knights, and at West Dean, the flowers are of 
a much paler hue than when fully exposed to the light and air. 
Statistics. In England, in the neighbourhood of London, are various plants, from 6 ft. to 10 ft. 
or 12 ft. high ; in Sussex, at Kidbrooke, there is one 15 ft. high; in Buckinghamshire, at Temple 
House, one, 12 years planted, is 20 ft. high ; in Suffolk, in the Bury Botanic Garden, 12 years planted, 
and 13 ft. high, against a wall; in Worcestershire, at Croome, 30 years planted, 15 ft. high ; in Cum- 
berland, at Ponsonby Hall, 12 ft. high.—Jm Scotland, at Danibristle Park, 16 ft. high; in Aberdeen- 
shire, at Thainston, it barely exists, even against a wall ; in Argyllshire, at Hafton, 6 years planted, 
it is 9 ft. high ; in Perthshire, at Kinfauus Castle, § years planted, it is 5 ft. high; in Forfarshire, at 
Airley Castle, it is 12 ft. high, against a wall.—Jn Ireland, in the Glasnevin Botanic Garden, 12 years 
planted, it is only 4 ft. high; but the diameter of the trunk is 4 in., and of the head 9 ft. ; in Galway, 
at Coole, it is 7 ft. high. 
Commercial Statistics. Plants, in the London nurseries, of the species, and 
all the varieties, are Is. 6d. each, except R.h. macrophylla, which is 2s. 6d. ; 
at Bollwyller, the species and varieties are all 1 franc 50 cents each; at 
New York, plants of the species are 374 cents each.
