IPOM(EA HARDINGII. 
The stems do not naturally die down every year, as is usual with most 
tuberous-rooted plants, but in order to have good specimens they should be cut 
away, and new shoots encouraged to grow from the base. These shoots commonly 
grow rather luxuriantly, and should therefore be closely trained in a spiral manner 
round a barrel or some similarly formed trellis, which will soon be perfectly 
concealed by the number and breadth of the leaves. 
When vegetation first begins to move in the spring, all the mould should be 
shaken away from the roots, after which they may be repotted, in a moderately 
rich and open earth, using much smaller pots, and then placing them in a frame 
with a gentle bottom-heat. As they grow, and the roots fill the pots, others three 
or four sizes larger should be substituted. They do not flower well in a green- 
bouse unless kept rather close, and a stove will always suit them better. 
It is increased by cuttings of the less luxuriant shoots, put in sand and treated 
ill the ordinary manner.
