licles elongated, arched, cohering at top. h.%.G. Native of

Hedge Periploca. Shrub climbing. 
Cult. P. Greca and P. angustifolia are handsome, hardy, 
twining shrubs, well fitted for covering bowers or trellis work, or 
for training against a wall; these grow freely in common 
garden soil, and are increased readily by layers or cuttings. 
The P. levigata will require protection in winter, either by 
being planted in a greenhouse, or *ainst a south wall, in which 
latter situation it will require to be protected by mats in frosty 
weather, in winter.
