ENCYCLOPEDIA OF GARDENING. 
Place in cold frame until required for forcing, or remove to ordinary 
heated greenhouse in Jan., cold house in Feb. Temp. for forcing 
55° to 65°. Water moderately when first brought into forcing or 
greenhouse; freely when growth begins. Apply weak stimulants—} oz. 
of guano to gall. of water—when fiower spikes show. Remove to cold 
frame after flowering & plant out in sunny position in June. Let 
plants remain thus tor two years, then lift, place in pots, & use for 
forcing. Plants will not flower freely two years in succession when 
grown in pots. Propagate herbaceous kinds by division of the roots, 
Czt, to March; shrubby ones by cuttings of young shoots inserted in 
sandy soil under hand-light or in frame in shade, summer; also by 
offsets removed & planted in autumn.

borders or rockeries. Plant, April or May. prapogate by seeds, 
sown Feb. or March, in well-drained pots or pans in above compost, in 
temp. of 55° to 60°; transplanting seedlings an inch apart in 3-in. 
pots when large enough to handle, afterwards hardening off in cold
