THE NURSERY LIST. 2OI 



Hedera (Ivy). Araliaccce. 



Seeds. Layers. The rooted portions of the vine may be 

 severed and treated as independent plants. Cuttings may be 

 made in autumn from any firm shoots, and inserted in pots 

 or in the open ground. If they are placed in heat and kept 

 shaded until roots are formed, good plants are obtained much 

 sooner than when placed in a cold-frame or in the open air. 

 Named varieties are grafted on the stock of any common 

 strong climbing form. 

 Hedychium (Indian Garland Flower). Stitaminece. 



Seeds, rarely. Increased by dividing the rhizomes in 

 spring, when the plants are repotted. 

 Hedysarum. Legu-ininosce. 



Propagation is effected by means of seeds and division. 

 Helenium. Composite. 



Increased by seeds or divisions. 



Helianthemum, including Fumana (Rock -Rose, Sun-Rose). 

 Cistinece. 



The annuals are raised from seeds. The perennials may 

 also be raised from seeds, but it is better to trust to layers 

 and to cuttings, which will root freely in a sandy soil, if kept 

 shaded until established. 



Helianthus, including Harpalium (Sunflower). Compositce. 



By seeds, which may be sown in pots, and the seedlings 

 transferred, or in the open ground in spring. Also divisions. 



Helichrysum, Elichrysum (Everlastings). Composilce. 



The annual species and the varieties of //. bracteatum may 

 be raised from seed, sown in a light heat in early spring, 

 and afterwards transplanted ; or sown in the open ground a 

 little later. The perennial species are increased by cuttings 

 in spring, in a close frame without heat. 



Heliconia. Scitaminece. 



May be increased by seeds, but the best method is by div- 

 ision of the root stock in spring when growth commences. 

 Separate pieces may be placed in pots, and grown in a moist 

 stove temperature, repotting when necessary ; or they may 

 be planted out in the stove, if desired. 



Heliotropium (Heliotrope). Boraginece. 



Seeds. The common practice is to use cuttings. These 

 can be taken at almost any season, if good growing shoots
