or simple. Very few species of this large genus are in 
cultivation. They are propagated by seeds; or by firm 
cuttings of young shoots, inserted in sandy or peaty soil, 
under a hand glass, in a slight heat, in summer. I. decora 
is a very desirable greenhouse shrub of moderate growth, 
which flowers profusely in summer, and is one of the 
species most generally cultivated. The plants should be 
cut in, about February or March, and started in a little 
warmth, when any repotting should also be attended to. 
They may be hardened, to grow in a cold frame after- 
wards, and watered freely throughout the growing and 
flowering period. The wood should be thoroughly ripened 
by exposure, in autumn, and a season of rest allowed in 
winter. I. Gerardiana forms a compact bush in the 
open shrubbery, and is also well adapted for covering 
walls, where it makes better growths, and flowers more 
freely. It. is one of the hardiest species. Indigoferas 
succeed in a somewhat rough compost of turfy loam and — 
leaf soil. To insure an abundance of flowers, the wood 
must be well ripened.
