not be planted out the summer previous to forc- 
ing, for it is then impossible to get its long, thick 
roots into a pot of practicable size. With any 
in-door plant, a small pot not only is more conven- 
ient, but also helps the appearance of the plant. 
We must, therefore, repot the wistaria during 
the summer, as occasion demands, supplying at 
the same time plenty of food, for all this while 
the vine is preparing the next season’s crop. 
The plants are imported from Holland in large 
numbers each year, but there is no reason why 
any person should not grow and maintain his 
own. For a perpetual supply get a dozen or two 
small individuals of W. brachybotris, and keep 
them potted until large enough to force. After 
a plant has flowered, it should be given a two 
years’ rest. For this reason, a number of plants 
forced in regular sequence will be necessary to 
supply flowers every winter. 
A house with a night temperature of 55° is a 
satisfactory winter home for wistaria. Spray 
the plants three or four times each day for the 
first week, then gradually reduce the frequency of 
the sprayings until, by the flowering period, they 
are discontinued completely. When grown in 
pots, the vines require very little pruning, merely 
a shortening of the thin, straggling shoots. If
