and when the plants are of a sufficient size, they should be separated and planted 
singly in pots, in a mixture of loam and peat; and after they have recovered 
this shifting they should be removed to the stove, where they may remain until 
they have ripened their seed. The H. Syriacus or Althaea frutex, is the only 
hardy shrubby species. It will thrive well in any common garden soil, and may 
be raised in abundance from either seeds or layers. The different varieties of 
this plant may be grafted on each other, and cuttings planted under a hand¬ 
glass will strike root freely. The hardy herbaceous species, which are very 
showy, thrive best in a moist soil, but being rather tender, most of them require 
protection in severe winters; they are only increased by dividing the plants at 
the root in spring.— Ibid. 
Culture of Stock Gilliflowers. —The method to procure fine double 
Stock Gilliflowers, Brompton and Queen Stocks, is to make choice of such single 
flowering plants as grow near many double ones, for it has been observed, that 
seed saved from plants growing among double kinds, have produced a much 
greater number of double flowering plants than those which have been saved 
from plants separated from the double ones. Sow the seed in May, and after 
they have reached two or three inches high, they should be thinned, at least nine 
inches asunder, and the plants so taken out, may be planted at about six inches 
apart in the flower border. If the following winter should be severe, the plants 
should be sheltered by mats, and in the following May and June they will become 
the greatest ornament to the flower border. 
Fine double varieties may be propagated by cuttings, which take root readily, 
if planted under a hand-glass and shaded. The Annual or Ten-week-Stock 
should be sown at three or four different times, February, March, April and May ; 
the plants from the last sowing will continue to flower till Christmas. Care 
should be taken in preserving only such single flowering plants for seed, both of 
the Stock-Gilliflower and Ten-Week-Stock, as have flowers of a fine colour. All 
the biennial and hardy shrub species of Mathiola should be treated in the same man¬ 
ner as that recommended for the Stock-Gilliflower, and all annual species in the 
manner recommended for Ten-Week-Stocks. Fine double stocks may be planted 
in pots, in order that they may be sheltered by a frame during winter. M. 
fenestralis thrives best, if sown on rock-work. The greenhouse shrubby kinds 
thrive best in a light soil, mixed with sand, and cuttings will strike readily, if 
planted under a bell-glass.— Ibid. 
Culture of Wall Flowers. (Cheiranthus.) The hardy shrubby species, 
such as fine varieties of the common Wall flower, should be increased by young 
cuttings; which will soon strike, if planted under a hand-glass. The greenhouse 
or frame kinds will thrive in a very light rich soil; and young cuttings, planted 
in the same kind of soil, will strike most freely under a hand-glass. The peren¬ 
nial or herbaceous species may be increased by dividing the plants at the root, 
by young cuttings planted under a hand-glass, or by seeds. The biennial and 
annual species, only require to be sown in the open border; some of the ten¬ 
derer sorts, or those natives of warmer climates, may be sown in a gentle hotbed, 
in the month of March, and transplanted in the open borders about the middle 
or end of April. The whole of the species answer well to be planted or sown on 
rock-work, and even'the tenderer species will survive the winter in such a situa¬ 
tion.— Ibid.
