2. CISTUS HETEROPHVLLUS, Various-leaved Rock Rose- 



This plant has a tree-like appearance, with short stiff 

 branches, and although its leaves are so small the flowers 

 are nearly as large as any of the genus, and are of a lively 

 colour, they are produced from June to July. 



It is a native of the uncultivated hills in Algiers, and 

 therefore requires the protection of a frame or greenhouse 

 in the winter ; or if planted against a south wall, and well 

 covered with mats in severe frosts, it will succeed very well. 



It affects a light rich soil, or a mixture of sandy loam 

 and peat. It does not strike freely from cuttings, the 

 shoots being so short and hard that good ones are with 

 difficulty procured, those should be taken off before too 

 ripe, and planted under a hand-glass. Seeds are some- 

 times ripened, which is the best method of increasing it. 



3. HELIANTHEMUM RHODANTHUM, Dark rose-coloured 



Sun Rose. 



This is a very handsome flowering plant, and one of the 

 most ornamental of the species for adorning rock work. 

 It is also quite hardy, nothing can make a more brilliant 

 appearance than the various flowers of different colours, 

 with which the plant is decked every day for about two 

 months. It also makes a handsome appearance when 

 grown in a pot, in which it will thrive well, or on a dry 

 bank in the garden, as nothing is more injurious to this 

 family of plants than too much moisture, especially in 

 the winter, like most of this species. 



The present plant grows freely in a mixture of sandy 

 loam and peat, or any light sandy soil. Young cuttings
