HELIA'NTHUS. Sunflower. (From helios, 

 the sun, and anthos, a flower; in reference 

 to the opinion that the flowers turn round 

 after the sun. Nat. ord., Composites [Aster- 

 acese]. IAmi.,ld-Syngenesia %-Superflua.) 



Hardy herbaceous plants, all yellow-flowered ; 

 well fitted for the back of flower- borders and the 

 front of shrubberies, where such modes of plant- 

 ing prevail. The annuals, such as the common 

 Sunflower, should be sown in a slight hotbed, and 

 afterwards transplanted ; the perennials must be 

 divided in the spring ; common, good soil ; a few 

 of the tenderest want a little protection in very 

 cold and wet winters.

HELICHRY'SUM. (From helios, the sun, 

 and chrysos, gold ; referring to the beauty 

 of the flowers. Nat. ord., Composites 

 [Asteracese]. Linn., 19-Syngenesia 2- 

 Superflua. Allied to Aphelexis.) 



Many may be raised from seed ; others, such 

 as hardy and greenhouse herbaceous, by division 

 and cuttings in spring, in sandy soil, under a 

 hand-glass ; evergreen shrubs from the Cape, if 

 small side-shoots are taken off when getting firm 

 at their base, will strike freely in sandy, peaty 

 soil, under a bell-glass ; peat and loam, three of 

 the former to one of the latter. Temp, for 

 greenhouse kinds, winter, 40 to 45. Stee'chas 

 is the hardiest shrubby kind, flourishing in a 

 sheltered place in dry, calcareous soil. Angusti- 

 fo'lium, conge'stium, and fru'ticans are the 

 next in point of hardiness, and probably would do 

 on a conservative wall.
