530 SPIRAEA 



the previous year; petals overlapping. It is at its best in June. The specific 

 name refers to the leaflike bracts on the stalks of the lower flowers. 



A native of Japan ; first introduced by Siebold to his nursery at Leyden, 

 and originally sold as " S. rotundifolia alba/' It is sometimes injured by 

 late frosts, but when these are escaped, few June-flowering shrubs are mo.re 

 lovely. The flower-clusters are all borne on the upper side of the horizontal 

 or arching branches. It is perfectly hardy, but needs liberal conditions at 

 the root, even more than the majority of Spiraeas do. The great thing is to 

 get a comparatively few long shoots rather than a crowd of small twiggy 

 ones. Old shoots should be 'removed as soon as they produce nothing but 

 twiggy shoots. 



S. BULLATA, Maximowicx. 



(S. crispifolia, Hort?) 



A dwarf shrub of very compact, rounded habit, rarely more than 12 or 

 15 ins. high ; branches erect, covered with rusty coloured down. Leaves 

 \ to i in. long, almost or quite as much wide; broadly ovate, often recurved, 

 coarsely and irregularly toothed, and nearly or quite smooth on both surfaces 

 except for a few hairs at the base and on the stalk; nerves prominent beneath. 

 Flowers scarlet rose, small, produced towards the end of July in great 

 numbers in flat branching corymbs at the end of the current season's 

 growths; flower-stalks downy. 



Native of Japan, and in cultivation by 1881. It is one of the dwarfest of 

 Spiraeas and one of the prettiest ; very suitable for the rock garden, or 

 wherever small dainty shrubs can be accommodated, and protected from 

 stronger growing neighbours. It is a near ally of S. japonica, and may be 

 a garden form of that species raised in Japan. The old flowering growths 

 may be cut back in spring. The specific name refers to the puckering of the 

 blade of the leaf, often noticeable between the veins. The plant is almost 

 hidden by its flowers in July. 



S. CANA, Waldstein. 



A shrub 3 ft. or more 'high and as much through; of dense, twiggy habit, 

 the young shoots round and covered with a thick grey down. Leaves 

 narrowly oval or ovate, tapering at both ends; to I in. long, about half as 

 wide; nearly always entire; covered on both sides, but especially beneath, 

 with a grey silky down. Flowers dull white, j in. across, produced during 

 May at the end of short leafy twigs in dense umbel-like racemes f to 

 i in. wide. 



Native of -S.E. Europe; introduced in 1825. The leaf is very like that of 

 Salix repens in its dense grey down, not, however, so silvery. One of the 

 least attractive of the Spiraeas, but of neat habit and quite hardy; also 

 distinct in the character of its leaves. 



S. CANESCENS, Don. 

 (S. flagelliformis, Hart.") 



A shrub varying considerably in height; at its tallest 12 to 15 ft. high, 

 more often 6 to 8 ft. high; the main stems erect, but producing towards the 

 top slender, arching or pendulous branches growing 3 ft. or more long in 

 one season; the young branches ribbed and downy. Leaves \ to i in. long, 

 \ to in. wide; oval or obovate, usually blunt and toothed at the apex, and 

 always more or less tapering to the very short stalk at the base; dull green 

 and with some down above, grey and more or less thickly downy beneath.
