The Broom which forms the subject of our illustration, 
an old favourite in gardens, is useful in flowering at a 
season, from the end of June to August, when the majority 
of shrubs have gone out of bloom, Its tall erect racemes 
make it very distinct among the hardy Brooms. The 
wealth of blossom is followed by a great quantity of seed 
which enables the stock to be easily renewed. But this 
excessive fertility is associated with a tendency to be short- 
lived, and it is therefore well to go over the plants as soon 
as the flowers are past and cut away all save a few of the 
old racemes. As the flowers are borne on the growths of
