IPOMCEA HARDINGII. 
The stems do not naturally die down every year, as is usual with mos 
tuberous-rooted plants, but in order to have good specimens they should be cu 
away, and new shoots encouraged to grow from the base. These shoots commonl] 
grow rather luxuriantly, and should therefore be closely trained in a spiral manne: 
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 b 
shaken away from the roots, after which they may be repotted, in a moderateh 
rich and open earth, using much smaller pots, and then placing them in a fram* 
with a gentle bottom-lieat. As they grow, and the roots fill the pots, others thre< 
or four sizes larger should be substituted. They do not flower well in a green 
house 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 treate< 
in the ordinary manner.
