May.] FLOWER-GARDEN, 397 
Sowing Perennial Flower-Seeds, Sfc. 
The seeds of most kinds of perennial and biennial flower-seeds* 
may yet be sown, as directed in page 353; but they will require 
occasional watering, till up and well established in the earth. 
Propagating Double Scarlet Lychnis. 
This beautiful flowering plant may now be propagated, by cuttings 
of the stocks, as well as at an earlier period, by slips from the root. 
Towards the latter end of the month, let some of the young flow- 
er-stalks be cut into lengths of six or seven inches, and planted in 
a shady border of rich light earth, leaving one or two joints of each, 
cutting above ground; close the earth well about them, water them 
gently, and if bell or hand-glasses are placed over them, their root- 
ing will be greatly facilitated thereby. 
The Hesperis matronalis, or Garden-Rocket. 
The double white, and double purple varieties, of the garden 
rocket, are extremely beautiful and fragrant; I have not yet had 
the pleasure of seeing one of them in this country, nor have I been 
able to learn that such is to be found on this side the Atlantic; 
however, it is to be hoped, we shall soon obtain that charming; 
showy, and delightful flower. It is perfectly hardy and may be 
cultivated at this season, as above directed, for the double scarlet 
lychnis, or by slips or offsets from the root, taken off and planted, 
either in spring or autumn; it does not prosper well, except when 
annually slipped or propagated by offsets; for the old roots are 
very subject to decay, especially the double varieties; the single 
sorts are much more permanent and easy of culture. The ladies 
of Europe are extremely fond of it, whence it obtained the name of 
Dame's- Violet, or Queen's Gillyflower. 
Double Wall-flowers and Stock-gillyflowers. 
The fine double wall-flowers, and double stock-gillyflowers, may 
now be propagated by young slips of the present year: chuse those 
of short and robust growths, from four to five, or six inches long, 
and let them be carefully slipped, or cut with a knife from the mo= 
ther plants. Take the lower leaves off, so that there may be two, 
three, or four inches of a clean stem to each, and plant them in a 
shady border or in pots, inserting them into the earth up to their 
leaves; then give some water, and be particular to shade them, 
from the mid-day sun, till they have taken root. Water them oc- 
casionally during summer, and in September, such as are planted 
in borders, may be taken up with balls of earth and potted, in order 
to be placed in frames, Sec. for protection from the winter frosts. 
The double varieties are accidentally produced from seed, and \% 
is very rare to meet with such, among seedling plants of the wall-
