bags into which they are put are correctly 

 marked. All that is known of the parent 

 plant should be added, if it is other than a 

 common kind, including the soil in which 

 it is found. When collected, the seeds 

 should be carefully dried. When they 

 belong to pulpy fruit, separate grains from 

 pulp as soon as decomposition begins, and 

 dry before placing them in bag. 



Seeds for Trees, Where to Buy. 



The seeds of a large variety of trees and 

 shrubs can always be obtained from Messrs. 

 Viccars, Collyer, and Co., Central Hall, 

 Leicester, at rates varying from 4d. to 

 I os. 6d. per oz. in one case, and 12s. 6d. 

 in another. The price per packet for some 

 varieties range from 6d. to 2s. 6d. As 

 prices can always be obtained on applica- 

 tion, and will in all probability be subject 

 to variation from numerous causes, it is not 

 desirable to state them here at length. 



Sempervivum(^. ord. Crassula'cea). 

 A large genus of shrubby herbs of curious 

 form and habit, mostly hardy perennials, 

 although some require the protection and 

 warmth of a greenhouse. An example, 

 likely to be familiar to all, may be found 

 in Sempervivum tectorum^ the Common 

 Houseleek, or Sengreen, which grows on 

 roofs and the top of thick walls, and often 

 increases to such an extent as to cover a 

 considerable area. The flower is red, the 

 leaves ciliated at the edges, and pale green 

 in colour with a brown tip. Sempervivums 

 are well suited for rock-work ; they like a 

 sandy soil, and are propagated by offsets 

 taken from any old-established plant. 



Senecio {not. ord. Composi'tss). 



A very large genus of annual, biennial, 

 and perennial plants, some hardy and fit 

 for outdoor culture, while others are only 

 suitable for the greenhouse or hothouse. 

 The common names are Groundsel and 



Ragweed or Ragwort. The weed so well 

 known in the garden as Groundsel is 



HOUSELEEK. 



Senecio vulgaris, the plant called Ragweed 

 being S.Jacobaa. The Senecios in cultiva- 

 tion, and these are by no means numerous, 

 like a good loam. The annual species 

 are, as a matter of course, propagated by 

 seed ; perennials by the division of the 

 roots. S. elegans is a species suitable for 

 garden culture. It bears a purple flower, 

 but some of its varieties have flowers white 

 and deep red in colour. One variety of 

 S. degans is known as "American 

 Groundsel " ; the blossom is double and 

 of a pretty purple colour. This is best 

 suited for outdoor culture by amateurs. 

 S. pulcher, with purple petals ranged 

 round a yellow disc is an excellent peren- 

 nial species for borders.
