THE NURSERY-LIST 331 



Hedysarum. Leguminosce. 



Propagation is by seeds and division. 



Hedyscepe. Palmacece. 



Seeds. See Palms, page 377. 



Helenium. Composites. 



Propagated by seeds, cuttings, and division. 



Helianthemum (Rock Rose. Sun Rose). Cistaceoe. 



Propagation is easily effected by divisions, from greenwood cut- 

 tings, and by seeds. 



Helianthus (Sunflower). Composites. 



Propagated by seeds, which may be sown in pots and the seedlings 

 transferred, or in the open ground in spring ; also by divisions. 

 Of perennial sorts, use the underground shoots or " creepers," 

 treating as for cuttings. Some of them (as the Jerusalem arti- 

 choke) bear subterranean tubers. See Artichoke. 



Helichrysum, Elichrysum (Everlasting). Compositoe. 



The annual species may be raised from seed in early spring and 

 afterwards transplanted ; or sown in the open ground when weather 

 is warm. The perennial species are increased by cuttings in spring 

 under glass. 



Helicodiceros. Aracece. 



Propagation as for arum, by offsets or by seeds when procurable. 

 See Aracece, page 239. 



Heliconia. Musacece. 



Multiplied by dividing the rhizome, and by seeds. 



Heliopsis. Compositoe. 



Propagated readily by seed and division. 



Heliotropium (Heliotrope). Boraginacece. 



The common practice is to use cuttings, taken at almost any 

 season if good stout growing shoots are to be had. They start 

 readily in sand on a cutting-bench, or under a frame. Shade for a 

 time. Plants for bedding are struck in late winter from stocks 

 which are in a vigorous condition. For winter flowers, cuttings 

 may be taken in July. Seeds are also employed.
