SELECTION OF PLANTS. 73 



will find an Observation on the Pelargoniums, or Stork's 

 Bill. 



C^r" There are a great variety of the Pelargoniums, and 

 every year produces new ones. 



If the reader will refer to two choice Selections in this 

 work, he will discover many fresh ones have been recently 

 raised from seed. 



217. CENTAUREA RAGUSINA, or White-leaved Centaury. 



This, though considered a hardy greenhouse plant, will 

 bear the cold of our ordinary winters in the open air, pro- 

 vided it be planted in dry lime rubbish, and sheltered. 

 It may be increased from slips, or cuttings from the 

 young branches which appear not likely to shoot up into 

 flower. In the autumn, if it is in a pot, it should be 

 moved into a warm aspect, and as our winters are so un- 

 certain, it is the safest method to shelter it. 



It blows in June and July, is a native of Crete, and 

 first brought to England in 1715. 



It belongs to the 1 9th Class, under the head " Synge- 

 nesia Frustranea." 



218. HELIOPHILA ARABIOIDES, or Blue-flowered 

 Heliophila. 



This pretty little Annual should be raised in the same 

 way as other half-hardy Annuals, such as China As- 

 ters, &c. 



The bed that these Annuals are raised in should be a 

 moderate heat, otherwise some of them will be drawn up 

 too weak. 



It blows in June and July, is a native of the Cape, and 

 first brought to England in 1778.
