Helianthus 



I 406 ) 



Helianthus 



out of a pot with the ball of soil intact. They 

 should always have full sun, but as the blossoms 

 are very fleeting they ought not to be planted 

 where flowers are required in the afternoon. They 

 may also be grown on rather flat roofs with about 

 4" of soil. 

 Principal Species and Varieties : 



formosum, 4', Je. , yel. 

 (;/. Cistus formosus). 



oeymoides, 2', Je., yel. ; 

 several vars. , such as al- 

 ga rveuse and eandidum. 



l>olil'olium, 1', Je., wh., 

 drooping, 



roseum, ro. 



vulgare, Je., yel., trail- 

 ing. A very variable 

 species, from which 

 most of GUI' garden 

 Heliauthemums have 

 come. Many colours. 

 Seedlings give good 

 flowers, but two of the 



best of the doubles are 

 that called amabile or 

 mutabilefl. pi., sc. , and 

 its yel. sport Jubilee. 

 Others are Mrs. C. W. 

 Earle, hyssopifolium, 

 macranthum, and jnu- 

 tabile. For other 

 nnmed Helianthemums 

 consult nurserymen's 

 catalogues, but cro- 

 ceum, Fireball, Gold- 

 en Queen, Innocence, 

 Pink Beauty, and Sul- 

 phur Gem would make a 

 good selection of singles. 



principally adapted for large borders, or for wild 

 gardens, especially those which are of rambling 

 habit at the root, sncli as H. rigidus and its forms. 

 These may be confined at the root, but in that case 

 require good feeding. 



Propagation. The perennials by seeds sown 

 under glass in spring or summer, or by division of 

 the roots in autumn or spring. The annuals by 

 seeds sown early in spring in a hotbed under glass, 

 I and pricked off into small pots, to be planted out 

 in May ; or sown in April or May where they are 

 to bloom. 



Soil. The Helianthuses like a rich, well dug 

 soil, with plenty of decayed manure beneath. 



Other Cultural Points. The Sunflowers ought 

 never to suffer from drought when growing, and 

 the tall forms of H. annuus, the Common (annual) 

 Sunflower, must have good treatment if wanted of 

 imposing dimensions. The perennial species also 

 respond to good treatment, and all should be 

 properly staked in good time.
