SELECTION OF PLANTS. 7 



20. COREOPSIS VERTICILLATA, or Whorled Coreopsis. 



This is a hardy Perennial, which blows from July to 

 October, and is propagated by parting the roots in the 

 spring. 



It is a native of North America, and was first brought 

 to England in 1759. 



It belongs to the 19th Class, under the head " Synge- 

 nesia Frustranea." 



21. SAPONARIA OCYMOIDES, or Basil Soap-wort. 



This plant is extremely hardy, and thrives luxuriantly in 

 almost any situation ; it is propagated by parting the roots, 

 or cuttings. The bloom is pale pink, and flowers from 

 June to August. 



It is a native of Switzerland, and was first brought to 

 England in 1768. 



It belongs to the 10th Class, under the head " Decan- 

 dria Digynia." 



22. OXALIS VERSICOLOR, or Striped flowered wood 

 Sorrel. 



This is a hardy greenhouse plant, but will with care 

 grow in the open ground, if planted in a warm situation, 

 at any rate it should be sheltered in the winter. If it is 

 shaded whilst in bloom it will appear to more advantage, 

 as it always looks best before the blossom expands, which 

 it readily does when exposed to the sun. 



In order to have a succession of these plants, the way is 

 to plant the pea-like tubera or knobs by which the plant 

 is propagated in pots filled with loam and bog earth. 



It blows in March and April, and is a native of the 

 Cape.
