THE FLOWER GARDEN. 
September lift the plants carefully from the nursery bed and 
replant them in their flowering quarters, sunny beds or borders. 
Make the soil firm, so that the growth may be hardy and 
sturdy and better able to resist the frost. Do not make the 
mistake of allowing the seedlings to remain in the seed bed 
till they are planted in their flowering quarters. Plants so 
treated produce tap-roots and straggly lanky stems, and rarely 
give satisfaction. The double-flowered kinds may be increased 
by cuttings or slips, i.e., short side-shoots removed with a heel 
of the old stem. Insert these in a shady border or in a cold 
frame in August. While the single and double forms will on 
well-drained soils assume the character of perennials, and live 
for many years, yet the best results are obtained from plants 
grown as biennials. Wallflowers readily reproduce themselves 
from seed. C. Marshallii is a hybrid perennial wallflower, 
growing a foot high, and bearing orange flowers in spring. 
This is a neat and showy plant to grow on a sunny rockery. 
C. mutabilis (Changeable Wallflower) is another perennial 
species W'hich is remarkable for producing its early flow'ers of 
a cream colour, and the later ones purple or striped. Both 
are increased by cuttings inserted in cold frames in August, or 
by seed sown outdoors in April. 
A recent introduction is a new hybrid winter-flowering wall- 
flow-er called Cheiranthus kewensis. It is the result of a cross 
between C. Cheiri (Common Wallflower) and C. mutabilis 
(Changeable Wallflower), and bears flow’ers of various shades of 
sulphur, orange-yellow, and purplish-violet on slender stems 
from November to spring. The flowers are deliciously fragrant, 
and the plant is quite hardy, forming a perennial bush. Sow 
seeds outdoors in July to ensure plants for flowering in autumn. 
Chelone (Turtle-head; Shellflow r er).- — The Chelones are 
handsome and interesting hardy perennials, natives of N. 
America and members of the Foxglove order (Scrophulari- 
aceae). There are two species which are worthy of cultivation in 
large or small gardens, and these are C. Lyoni, pink, July to 
September, 3 to 4ft., and C. obliqua, violet-purple, summer, 2 
to 3ft. There is also a white variety of the latter species named 
alba. All are very elegant and graceful w hen in flower. They 
succeed well in good, deep, well-drained ordinary soil and a 
sunny position. Plant in autumn or spring. Increased by 
seeds sown outdoors in April, or in a cold frame in September, 
planting the seedlings out the following April ; cuttings in 
sandy soil in a cold frame in summer ; and division of the roots 
in October or March. 
Chenopodium (Goosefoot). — Two species of this genus 
are grown as ornamental plants in the flov. cr garden. Both
