be sown in April and plants put out 1 foot apart in rows 
2 feet asunder. During growth the stems should be left 
uncovered, not earthed up. 
LABURNUM.—The species of these well- Lcineited flower- 
ing trees are raised from seed sown outdoors in March. 
‘The varietal forms are perpetuated by budding on stocks 
of the common Laburnum in July or by grafting in 
March. 
LACHENALIA.—Offsets of these desirable greenhouse 
bulbous plants are produced pretty freely by old bulbs 
and—except the very smallest—flower the following 
season. Seedlings blossom about the second year from 
the time of sowing the seed. 
LAGERSTROMIA (CRAPE MyrtLe).—Rather firm side- 
shoots should be taken off with a heel in spring and 
inserted in sandy peat, covered with pure sand, plunged 
in bottom heat with a bell-glass over them. 
LaNTANA.—Cuttings of non-flowering shoots from cut- 
back plants root readily in spring or autumn in a close 
frame with bottom heat. Seed may be sown in gentle 
heat in March. 
LapAGERIA.—Seed sown in gentle heat soon after 
ripening may be employed, but the usual nursery method 
of increasing the white-flowered form L. alba and choice 
varieties of L. rosea is to form a raised bed about 5 feet 
from the glass roof composed of 3 parts peat, 1 part 
loam, and a liberal admixture of silver sand. In this 
the parent plant is placed, and strong, long, healthy 
shoots are laid down, tongued on the underside at 
intervals in the same way as Carnations, fixed in 
position with pegs, and just covered with the compost. 
The leaves are not removed, but left protruding, sus- 
taining no injury. Thus growths are induced to break
