The soil in which this rare and pretty shrub does best is a
brown, fibrous peat, intermingled with sharp sand.
RHODODENDRON.
RHODODENDRON ARBORESCENS (_syn Azalea arborescens_), from the Carolina
Mountains (1818), is a very showy, late-blooming species. The white,
fragrant flowers, and noble port, together with its undoubted hardihood,
should make this shrub a general favourite with cultivators.
R. CALENDULACEUM (_syn Azalea calendulacea_), from North America (1806),
is another of the deciduous species, having oblong, hairy leaves, and
large orange-coloured flowers. It is of robust growth, and in favoured
situations reaches a height of 6 feet. When in full flower the slopes of
the Southern Alleghany Mountains are rendered highly attractive by
reason of the great flame-coloured masses of this splendid plant, and
are one of the great sights of the American Continent during the month
of June.
R. CALIFORNICUM.--California. A good hardy species with broadly
campanulate rosy-purple flowers, spotted with yellow.
R. CAMPANULATUM (_syn R. aeruginosum_).--Sikkim, 1825. A small-growing
species, rarely over 6 feet high, with elliptic leaves that are
fawn-coloured on the under sides. The campanulate flowers are large and
showy, rose or white and purple spotted, at the base of the three upper
lobes. In this country it is fairly hardy, but suffers in very severe
weather, unless planted in a sheltered site.
