rous flowers. It requires protection in the winter, and is 

 propagated and managed the same as the rest. 

 It is a native of the South of Europe. 



54. CISTUS ROTUNDIFOLIUS, Round-leaved Rock Rose. 



This plant makes a snug dwarf bushy shrub, and 

 flowers all the summer. It is nearly quite hardy. 



It affects a light sandy loam, and is readily increased 

 from cuttings, planted under a hand-glass in autumn, or 

 by layers or from seeds. 



55. HELIANTHEMUM ERIOSEPALON, Woolly -calyxed 

 Sun Rose. 



This plant is proper for rock work, or to grow in small 

 pots. It will bear the severity of the winter ; continuing 

 in bloom the most part of the summer. 



It affects a light sandy soil, with a mixture of peat. It 

 strikes readily from cuttings planted under a hand-glass. 



5^. CISTUS ACUTIFOLIUS, Acute-leaved Rock Rose. 



This is a free-growing but dwarf plant, quite hardy, and 

 thrives well in a light sandy soil, continuing to flower suc- 

 cessively nearly all the summer, and ripens its seeds well. 



Young cuttings planted under hand-glasses, in the 

 autumn, strike readily.* 



* In the winter of 1826, a great many species of Cistus were 

 tried in various situations in the open ground, and have been found 

 to succeed best and suffer the least from frost in a border with a north- 

 west aspect ; scarcely any of them were injured, though some of them 

 vrere of the tender sort; they had not the least covering or protection. 

 This may be accounted for by their being in ajraore dormant state, and 

 the wood more hardened to withstand the frost, as those in a southern 

 aspect, though partially covered, were injured much more, which can 

 only be accounted for by their being more in a growing state.
