338 APPENDIX. 



39. CISTUS SALVIFOLIUS, Sage-leaved Rock Rose. 



This plant is a native of several parts of Europe, and 

 succeeds well in the open air in a sheltered situation, 

 thriving well in common garden soil ; if grown in pots, a 

 mixture of sandy loam and peat is the best. 



It is propagated and managed the same as the rest of 

 the species. 



40. HELIANTHEMUM ROSEUM, Rose-coloured Sun Rose. 



This plant is a native of the South of Europe, and re- 

 quires a slight covering in severe frosty weather ; but will 

 endure our mildest winters without any protection. It is 

 a pretty plant, and will adorn rock work greatly, as it pro- 

 duces an abundance of flowers nearly all the summer. 



It is propagated and managed the same as the rest of the 

 species. 



41. HELIANTHEMUM PUNCTATUM, Spot-flowered 

 Sun Rose. 



This pretty little species is a native of France, a hardy 

 annual, and only requires to be sown in the open border in 

 April, and to be kept free from weeds. 



It will continue to flower all the summer, and will ripen 

 plenty of seeds. 



42. CISTUS UNDULATUS, Wave-leaved Rock Rose. 



This should be planted in a northern aspect in the gar- 

 den, where it will stand the whole of the winter without 

 the least protection ; whereas a southern aspect does not 

 suit it, as they all died when planted there, or were so 

 severely injured, they were not worth keeping.
