THE FLORAL WORLD AND GARDEN GUIDE. 127 



April, in sliallow pans or small pots, in a mixture of equal parts of peat, leaf- 

 mould, and silver sand, and place them in a moist heat of 60' to 70". It matters not 

 how this lieat is obtained, provided it is sweet, and the pots are near the glass. A 

 dung-bed in a common frame will answer as well as a tank in a propagating-house, 

 if the maniigement is good. When they have grown about two inches, trans- 

 plant them into their flowering-pots. It is the custom to put three plants in an 

 eight-inch pot, hut where good growing is the practice, one plant is found to be 

 quite enough, as it can soon he raide to fill the pot, and produce a profusion of 

 flowers. The soil for flowering them in should consist of four parts mellow loam, 

 two parts leaf-mould, and one part each of peat and silver sand, A steady heat, 

 the plants kept near the glass, regular syringing, and a little shading on sunny 

 days, and neat stakes as soon as the plants require support, are the several requisites 

 to success, which, with this beautiful plant, is well worth striving for. Tlie plants 

 you h ive singly in thumbs must be shifted to 48-size as soon as the thumbs are full 

 of roots. The achiraines does not require much moisture ; at the same time, neglect 

 of watering both at the root and overhead with the syringe will be sure to invite red 

 spider. 



Caladiums. — T. J. K. — The treatment of these beautiful plants was admirably 

 described bv one of the heads of dep irtments at Kew in the fourth volume of the 

 Floral World, page 179, and at page 115 of the same volume are some remarks 

 on their uses as bedders — remarks not then intended as prophetic, but which in 

 respftct of Battersea Park and the Parisian gardens have proved to be so. Your 

 caladiums Avill by this time require a shift on, and the soil should be fibrous 

 loam, peat, and leaf-mould, with the addition of sand. The great secret of success 

 is to keep them in a good heat, with plenty of atmospheric moisture and abundance 

 of water at the roots, shading from hot sunshine, and shifting on as fast as they fill 

 their pots w'irh roots. 



Double White Sweet Pea. — 3Irs. K., of Romford. — ^We have never met 

 with u double white sweet pea, and are in great doubt if such a thing exists. Pro- 

 bably it is the common white everlasting pea you are desirous of obtaining. If so, 

 you may obtain seed from Messrs. Jas. Carter and Co. Almost any nurseryman 

 can supplv plants, and in fact it ought to be found in plenty everywhere, tor it 

 is a fine thing. If any difficulty in obtaining it in your district, send to Messrs. E. 

 G. Henderson and Son, Wellington Road, St. John's Wood. 



GexNETYLLIs and llT.r)\noMX.—Iiocklocl(/e.— These two genera are closely alljed, 

 yet the same treatment will not do for all the species enumerated under them. The 

 points in which alone they diff"er — that is as to requirements— :ire as to the tempe- 

 ratures best adapted for them. As a rule the species of Genetyllis are green- 

 house shrubs, and as a rule the species of Hedaroma are stove shrubs, but 

 there are exceptions under both heads. The points in which they agree 

 are these, that they require a sound, but gritty loamy soil of a highly nou- 

 rishing character, as much air as their constitution will bear and the season will 

 allow, abundance of water while growing freely, and to be at all times guarded 

 against excessive damp either in the atmosphere or the soil. They belong to rather 

 dry climates, where, in the growing season, rain flills abundantly. Genetj^Uis 

 tulip f era is a favourite subject for exhibition, to grow it to a fine size and condition 

 is the work of some years. It requires a light airy greenhouse, and will do well 

 with such treatment as Epacrises and Cape heaths thrive under, except that it must 

 have a stronger soiL As for the getting up of specimens, that is a matter of stopping, 

 training, and tying, and on which books can afford but little aid. G. macrostegio 

 is a fine species, requiring the same treatment. Of the Hedaromas, K. latfolia, 

 H. pinifolia, and H. thymoides are the best. Treat them the same as the Gene- 

 tyllis, but with more heat. Where there is no stove these may do very well, with 

 coaxintr, in a warm greenhouse. 



Fifty Spking Flowers.— (?. S. Woodhtiry. — From the excellent lists by Mr. 

 Robinson, Mr. Williams, The O'Shane, and others tlnit have lately appeared, selec- 

 tions of spring flowers may be easily made. But here is a list of fifty prepared 

 during an inspection of a collection of upwards of 5000 species and varieties of 

 hardy plants at Messrs. E. G. Henderson and Sons' Nursery, St. John's Wood : — 

 Adonis vernalis, Alyssum saxitile compactum. Anemone nemorosa, Arabis albida, 

 Aubrietia deltoidea grandiflora, Aubriecia purpurea, Bellls perennis (various), Caltha 

 palustris fl'ire pleno, Cheirantlius alpinus, Cheiranthus cheiri (various), Dondia 

 epipactis, Eranthis hyemalis, Ficaria ranuuculoides, Helleborus niger, Helleborus
