Deherainia 



( 2S4 ) 



Delphinium 



DEHERAINIA. 



The only member of the genus (ord. Myrsinesc) 

 is a stove shrub. It thrives in a mixture of loam, 

 fibrous peat, and coarse sand, and is increased by 

 cuttings of ripe wood in sand, under a bell-glass 

 over bottom heat ; also by seeds. 



Only Species : 



smarag'dina, I!', grn. ; thick and fleshy. 



DELARBREA. 



The only cultivated species, spectabilis (ord. 

 Araliaceic) is an evergreen stove plant closely 

 allied to the Aralias. It is a handsome plant, and 

 if allowed will assume tree-like proportions. It 

 succeeds if treated like a warm Aralia. 



DENDROBIUM ATROVIOLACEUM (see p. 287). 



DELOSTOMA. 



A stove tree (ord. Bignoniaceic). Propagation 

 is by cuttings in sand, or very sandy soil, beneath 

 a bell-glass over bottom heat. A compost of 

 mellow loam, with some peat and sand, suits it. 



Principal Species : 



dentatum, aut., whitisli bl. 



DELPHINIUM. (LAHKsrun.) 

 Description. The Delphiniums, or Larkspurs 

 (ord. Kanunculaccic), rank among the best and 

 most effective of our summer flowers. The noble 

 hybrid perennial Delphiniums are of surpassing- 

 effect when well grown ; the various species o'f 

 perennial habit are often beautiful, and the annuals 

 are of much value for the garden or for cutting. 



Propagation. The perennials by seeds sown in 

 spring, or by division at that season ; the annuals 

 by seeds sown as directed for .annuals (half-hardy), 

 afterwards planting them out where they are to 

 bloom. 



Dclabechia (zee StorouUd). 



Delairia ncandcns (sec Scneriu milltaniuides). 



Soil. A rich, well-manured soil is required to 

 bring the Delphinium to perfection, and in dry 

 weather copious waterings of liquid manure may 

 bo applied if tall plants are wished. 



Other Cultural Points. The perennials should 

 be protected from slugs, and ought to be staked 

 early, the stems being fastened as they grow. If 

 the flower spikes are removed early, the side shoots 

 will come into bloom in autumn.

Hybrid Varieties : 



These are undoubtedly the finest, and many are 

 of wonderful beauty. The recent introduction of 

 white or whitish varieties will add much to their 

 value. Those who wish to purchase are recom- 

 mended to study the catalogues of nurserymen, ns 

 new varieties are introduced yearly. Those named 

 are all good.
