and flowering from May to August. 

 It seldom exceeds 1 ft. in height, but 

 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 Is. 6d. each ; 

 grafted standard high, they are from 2s. Qd. to 5s.: at Bollwyller, they 

 are 50 cents each ; and for two years' seedlings, 4 francs for 25.
