root freely, if planted under a hand-glass in a shady 

 situation, or in the sun with a mat thrown over the glass. 

 It is a native of Spain. 



4. CISTUS CORBARIENSIS, Mountain Rock Rose. 



This plant is one of the hardiest species of the genus, 

 thriving well in the common garden soil, where it is 

 not too stiff and moist, continuing to bloom for about 

 two months, and each day covered with a profusion of 

 handsome white flowers. The rose-coloured buds are

It is a native of mountains in the South of France 

 and Spain.

 under a warm wall it should be covered with a mat, and 

 a little dry litter about its roots. 



It affects a light turfy sandy loam and peat. Young 

 cuttings strike freely, taken off at a joint, and planted 

 under hand-glasses in autumn. It also ripens plenty of
