profusely laden with clusters 

 of pure white blossoms, de- 

 spite frosts or cold winds, 

 which play havoc with some 

 of the early kinds. 

 A free-growing species, 5 feet 

 high, with pretty flowers. 



A dwarf bush, 2 feet high, with 

 pretty cherry-pink flowers. 



A bold bush, 6 feet or more in 

 height. 



Grows 5 or 6 feet high. 



A dwarf species suitable for 

 rockwork. 



The shoots of this are slender 

 and arching so that it forms 

 a graceful freely - branded 

 shrub, some S to 8 feet in 

 hei|;ht. It is one of the best 

 Spiraeas. 



A well-known shrub, far better 

 known, however, under the 

 name of Spiraea arisefolia. 

 It reaches a height of 10 to 

 12 feet or even more, with 

 plume-like clusters of creamy 

 white blossoms. This is a 

 shrub for the smallest gar- 

 den. 



Forms a crowded cluster of 

 erect shoots 6 feet or so in 

 height, with each shoot ter- 

 minated by a dense spike of 

 flowers. It succeeds best 

 in damp soil. 



The slender arching shoots are 

 clothed with clusters of pure 

 white flowers in late May. 



Far better known under the 

 name of S. callosa than that 

 of japonica; it forms a 

 shrub S or 6 feet high with 

 brightly coloured flowers in 

 flattened clusters. There are 

 many distinct varieties, all 

 good, the best being alba, 

 a dwarf form with white 

 flowers ; Bumalda, also dwarf 

 with pink blossoms ; Anthony 

 Waterer, the richest tinted 

 of all dwarf kinds ; superba, 

 a deep tinted form of the 

 type; and glabrata, with 

 curiously broad leaves. An- 

 thony Waterer is especially 

 worth growing.
