FLOWERING TREES AND SHRUBS 181 



tiny bunches of bright rose-coloured flowers, and these 

 look all the more charming owing to the miniature size of 

 the shrub, its average height being about 12 inches. A 

 very interesting and valuable rock shrub, and one that 

 no doubt about its perfect hardihood need be entertained. 



S. CANA. Hoary-leaved Spiraea. Croatia, 1825. This 

 is a small, spreading shrub that rarely rises to more than 

 18 inches in height, with small, ovate, hoary leaves, and 

 pretty white flowers arranged in corymbs. For rockwork 

 planting it is one of the most valuable species, growing 

 freely and producing its showy flowers in abundance. 

 Quite hardy. 



S. CANTONIENSIS (syn S. Reevesiana). Reeve's Spiraea. 

 Japan, 1843. An evergreen or sub-evergreen species, 

 growing 3 feet high, with lanceolate leaves on long foot- 

 stalks, and large, pure-white flowers arranged in terminal 

 corymbs and placed on long peduncles. 



S. CHAM^DEIFOLIA (syn S. ceanothifolio) . Germander- 

 leaved Spiraea. South-Eastern Europe to Japan, 1789. 

 Grows about a yard high, with ovate, pubescent leaves, 

 and white flowers. It varies widely in the shape and size 

 of leaves. S. chamaedrifolia ulmifolia (Elm-leaved Spiraea), 

 a twiggy shrub, 3 feet high, with broad leaves and white 

 flowers, is from Siberia. S. chamaedrifolia crataegifolia 

 (Hawthorn-leaved Spiraea) is of stout, half-erect growth, 

 with rather stiff glaucous leaves that are oval in shape, and 

 bright-red or pinjs flowers in fastigiate panicles. From 

 Siberia (1790), and flowering at mid-summer. 



S. DECUMBENS (syn S. nana). Decumbent Spiraea. Tyrol. 

 This is the smallest-growing of the shrubby Spiraeas, rarely 

 attaining to a greater height than 12 inches. It is a neat 

 growing plant, with small oval leaves and white peduncu- 

 late flowers. For planting on the rockwork or in the front 

 line of the shrubbery this is an invaluable shrub, and 

 soon forms a neat and pretty specimen. It is perfectly 

 hardy.
