Ill 



There are varieties with long leaves and with round leaves. 



Culture. This is increased by laying down the young branches, 

 or one-year's shoots, which may be taken off in a twelvemonth, and 

 set where they are to remain, as they do not bear transplanting well 

 afterwards. The effects of drying winds should be guarded against 

 in the summer, and frosts in winter; the former by very moderate 

 waterings, and the latter by coverings of bark. The best season for 

 laying down is the autumn, and for planting out, the spring. 



This shrub is capable of bearing the open air, but requires a dry 

 soil and warm exposure. 



It is very ornamental in the fore parts of clumps or borders in 

 shrubbery and other ornamented grounds.
