SELECTION OF PLANTS. 331 



The soil the same as the rest of the genus. Cuttings 

 will freely strike under a hand-glass, but they must be 

 planted thin, or they will damp each other off. 



Many of these plants may be had at Messrs. Lee & Co/s, 

 Hammersmith ; or at Messrs. Whitley, Brames & Milne, 

 at Fulham. 



15. CISTUS POPULIFOLIUS, Poplar-leaned Rock Rose. 



A strong robust species. A native of the South of 

 Europe, and rather tender, as it will sometimes be injured 

 in very severe winters, if not protected with a mat. It 

 thrives well in common soil. If grown in pots, a mixture 

 of light loamy soil and peat will be proper. 



Its flowers are produced in May and June, and seeds 

 are frequently produced, which may be sown and managed 

 in the same manner as in No. 13. Cuttings of young 

 shoots strike freely, under a hand-glass, in September or 

 October, and when sufficiently rooted should be placed 

 under a frame during the winter. 



16. HELIANTHEMUM VERSICOLOR, Various- coloured 



Sun Rose. 



As the present plant is a native of the South of Europe, 

 it cannot bear the severity of our sharpest winters without

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

 loam. Cuttings strike freely under a hand-glass, if 

 planted in September or October.

 This plant is more scarce than many of the species, and
