HERBACEOUS PLANTS 157 



Oliverianum Alpinum. Should be grown 

 in the full sun or the lovely blue colourings will 

 never develop (see also Annuals and Biennials). 

 o.v.Gaillardia grandiflora. These are most artistic 



flowers, and of easy culture. 



*Gerbera Jamesonii. The lovely new hybrid varieties of 

 this plant are destined to become very popular 

 when they are better known. They are not 

 quite hardy and are procured from seed. 

 *Q.-R.Gypsophila paniculata. Too well known to need 

 description. One of the most helpful flowers to 

 both amateur and professional florists. Never 

 use much GypsophUa when mixing it with other 

 flowers. A few sprays tend to lighten all work, 

 but a cloud of it spoils everything. 



*o.*.Gy psophilapaniculatajl.pl. Adouble variety of above. 



o.E.Helenium Bigelowi. A very handsome plant, produc- 



ing great clusters of yellow flowers with jet-black 



eyes. 



o.E.Helianthus (Herbaceous Sunflowers) multiflorus, 



Golden bouquet. 



o.v.He2ianthus (Herbaceous Sunflowers) multiflorus, 

 Soleil d'Or. 

 These two are both beautiful additions. 



*Helianthus rigidus sparsifolia. A very late variety, 

 indeed it flowers right up to the time when the 

 frost cuts everything down. 

 o.x.Heliopsis scabra, Ben Ladhams. A charming 



perennial. 

 Heleborus (Christmas Rose) niger maximus. 



angustifolius (the St. Brigid's Christmas 



Rose). 

 These are the two best for cutting.
