Cult. This is an elegant shrub when in flower, being clothed 

 with beautiful yellow flowers during the months of May and 

 June. It is sufficiently hardy to stand our climate without any 

 protection, and therefore is a great acquisition to hardy flower- 

 ing shrubs. It is increased by laying down the shoots, or young 

 cuttings will root if planted in sand under a hand-glass.

Cult. The species of this genus are very elegant, but pre- 

 served with difficulty. They grow best in light soils, and they 

 should be increased by seed, as dividing the plants at the root, is 

 apt to injure them.
