of its extra
brightness as seen by gaslight--this fact adds much to its value for
indoor decoration.

It may be grown in any kind of garden soil, needing nothing at any time
in the way of special treatment; but if it is supplied with a little
manure it will pay back with interest, in the form of extra-sized
bunches and brighter flowers.

_C. r. albus_ is a white-flowering kind of the above; its main points of
difference are its paler green foliage, smaller sized corymbs, shorter
growth, and rather later season of bloom.

_C. r. coccinea_ is another kind; the specific name is misleading. It is
not scarlet, but nearer a rose colour, and when compared with the
typical colour it appears much inferior; still, it is a good variety.
All the three colours, when grown side by side, are very showy when in
bloom.

This species, with its varieties, may be easily propagated by root
divisions at any time from late summer to spring; the long fleshy roots
should not be broken more than can be helped; every piece with a crown
on it will make a flowering plant the first season.

Flowering period, June to September.

Cheiranthus Cheiri.

COMMON WALLFLOWER; _Nat. Ord._ CRUCIFERAE.

This well-known evergreen shrub (see Fig. 24) is more or less hardy in
our climate, according to the conditions under which it is grown.
Although a native of the South of Europe, it rarely happens, however
severe the winter may be in this country, that we are totally deprived
of the favourite bouquet of Wallflowers in winter or early spring, while
it is equally true that, during the hard weather of one or two recent
winters, in numerous gardens every plant was killed. In favourable
seasons its blooms are produced throughout winter, but the full blow
comes in April. Three hundred years ago it was known by its present
name; in this respect it is a rare exception, as most flowers have many
and widely different names, especially the "old-fashioned" sorts, so
that often the varied nomenclature hinders the identification of the
species. At one time the Wallflower was called the "Gillyflower," but
the name is now only applied to a biennial and single-flowered variety
of the stock--a near relation of the Wallflower. More than 200 years ago
Parkinson wrote, "Those Wallflowers that, carrying beautiful flowers,
are the delights and ornaments of a garden of pleasure."
