OF ORNAMENTAL PERENNIALS 103 
found that it will succeed very well in the open air. It is a biennial, and the best mode of treating it is to sow 
the seeds in pots, either in autumn or very early spring. In the first case, they should be kept under shelter all 
the winter, and planted out in spring ; and in the second, the pots should be plunged in a hotbed as soon as the 
seeds are sown in February, and the young plants should be planted out in May. The species is a native of the 
Cape of Good Hope, and it was introduced in 1775. 
a— SILENE PENNSYLVANICA, Micha. THE PENNSYLVANIAN CATCHFLY, OR AMERICAN 
WILD PINK. 
Synonymes. — S. incamata, Lodd. ; S. caroliniana, Walt. 
Ekgravings. — Bot. Reg, t. 247 ; and out Jig. 2 in Plate 25. 
Specific Cuuucteu. — Viscidly pubescent. Radical leaves spatu- 
late ; cauline ones lanceolate. Petals obtase, somewhat emarginate, 
subcrenate. 
Description, &c. — This is a dwarf plant, with clusters of large pink flowers, which is vety ornamental for 
rockwork, or in beds in geometrical flower-gardens. It is a hardy perennial, propagated by dividing the roots ; 
and it will grow in any garden soil, and common situation. It is a native of Pennsylvania, and was introduced 
in 1806. It seldom grows above three or four inches high ; but it bears a great profusion of flowers, each of 
which is as large as the flower of the wild pink.

ENGRiYiNGS. — Bot. Mag. t. B07; Swt. Brit. Flow. Gard., 2d ser., 
t. 26,3; Bot. Reg. t. 1989; and onvfig. 7 in Plate 25. 
Specific Character. — Plant very smooth and glaucous. Stems 
branched. Leaves elliptical, pointed, upper ones rather cordate ; 
flowers large, disposed in a terminal panicle. Calyx long, cylindrically- 
clavate, downy ; petals two-lobed ; lobes broad, obovate, with two- 
parted appendages. (G. Don.) 
Description, &c. — This is the most compact-growing of all the kinds of Silene ; and it has broad, firm, well- 
coloured leaves, which contrast well with its large, pure white flowers, with pinkish calyxes, and which become 
pink in dying ofi" ; it also continues a long time in flower. It should be grown in a light, but rich loamy soil, 
when it will flower luxuriantly ; but in poor sandy soil, or on rockwork, the flowers are small, and the whole 
plant becomes dwarfed. It is a native of America, where it was discovered by Toumefort ; and it was intro- 
duced by Mr. Hunneman in 1796. 
10.— SILENE REGIA, Sims. THE ROYAL CATCHFLY. 
Sysonyme. — S. virginica, var. lUinoensis, Michx. lanceolate. Flowers large, panicled. Calyx downy, long, tubular. 
Emgravings. — Bot. Mag. t. 1724; Swt. Brit. Flow. Gard., 2d Petals ob-lanccolate, undivided, crowned with bicuspidate appendages, 
ser., t. 313, and om fig. 6 in Plate 25. Stamens very long. ( G, Don.) 
Specific Character. — Plant clammy, pubescent. Leaves ovate- 
Description, &c. — This splendid plant in rich soils grows three or four feet high ; but in poor soils it is 
of comparatively very low growth, though it still produces a profusion of its splendid flowers. It is quite hardy, 
and will grow in any common garden soil and situation. The stems are hollow and jointed ; and the leaves of a 
yellowish green. It thrives most in a compost of peat and loam, and it is propagated by division, as it rarely 
ripens its seeds in this country. It is a native of North America, where it was found on the banks of the 
Mississippi, growing in great abundance. It was introduced in 18II.
