is very ornamental on rockwork, or 
when grafted on the laburnum, stand- 
ard high. Of all the different species 
of Cytisus, when grafted standard 
high, this forms the most graceful 
tree; and a plant of it covered with 
its purple flowers, placed on a lawn, 
or in a border near a standard of 
Genista triquetra, covered with its 
golden yellow flowers, will produce a very striking 
effect. Plants, in the London nurseries, are 1s. 6d. each ; 
grafted standard high, they are from 2s. 6d. to 5s.: at Bollwyller, they 
are 50 cents each; and for two years’ seedlings, 4 francs for 25.
