GARDEN FLOWERS. 189 



HELICHRYSUM. [Composite.] A genus comprising 

 many species, including the well-known annual Everlast- 

 ings, and a few half-hardy perennials. The common an- 

 nual Everlasting, and some allied plants, though introduced 

 from New Holland, are treated as half-hardy annuals, being 

 sown in the open borders in May, or, for earlier blooming, 

 on a gentle hot-bed in March, and transplanted in May. 

 They come into bloom at an advanced period of the sum- 

 mer, and continue a succession of blossoms until destroyed 

 by the frosts of autumn.

 seedsmen. FT. incurvum is a variety of bracteatum, produ- 

 cing flowers of every shade of yellow, sulphur, cream, white, 

 pink, rose, red, and crimson. 



HELIOPHILA. [Cruciferae.] Hardy annuals, some of 

 which are pretty flower border plants. They should be 

 sown in the open ground in May, or, for earlier blooming, 

 in April, under cover, and afterwards planted out. Rather 

 sandy soil is preferable, and they like exposure to sun. 

 Two or three are delicate greenhouse shrubs, but not of 

 much importance.
