ROSACE.E. I 1 5 



They appear in May and June. Native of the mountains of 

 central and southern Europe, and of Britain, but only locally. 

 A pretty species for rockwork or the front of borders. 



Spiraea. — This genus is a considerable one, but a large 

 number of the species are shrubs. Of hardy herbaceous plants 

 there are, however, several very beautiful — even splendid; and 

 it may be said of all the species that they are worthy of a place 

 in any garden. They are better fitted from their style of growth 

 for culture in borders or beds than on rockwork, unless it is of 

 great extent, when they may very properly form the centre of 

 groups. The more vigorous species are admirable for intro- 

 ducing into open moist woods, the banks of streams and ponds, 

 and moist glens. All are easily propagated by division. 



S. Aruncus {Goafs-beard S.) — This is the most vigorous and 

 bulky of the group. It grows erect, with stout stems 4 or more 

 feet high, densely furnished with immense tripinnate leaves. 

 The flowers, in bold yet graceful spikes, are white or creamy 

 white, and appear in June and July. One of the best for 

 naturalising, and for introducing among evergreen shrubs. 

 Native of Siberia. 



S. Filipendula iDropivort S.) — This is a British species, and 

 in the double form is not uncommon in gardens. The leaves 

 are dark green, pinnate, the leaflets oblong and deeply cut. 

 The stems are erect, very sparingly furnished with leaves, about 

 18 inches high, bearing corymbs of beautiful creamy-white 

 flowers often tinged with red. The double variety is the most 

 ornamental. Flowers from early summer till late in autumn 

 in moist good soil. 



S. lobata, syn. S. venusta [Lobcd-kaved S.) — This is a very 

 handsome species, not so well known in gardens as the last two 

 and Ulmaria. It grows from i}4 to 2 feet high, with some re- 

 semblance to the Meadow-Sweet, but it is more nearly related 

 to the next species. The leaves are pinnate, the side leaflets 

 three-lobed, the end one seven-lobed. The flowers are beauti- 

 ful deep rose, in rather dense panicles at the top of the stem, 

 which partakes of the colour of the flowers to a certain extent 

 downwards. They appear in July and August. Native of 

 Siberia. This is a beautiful and choice plant, not nearly so 

 well known as it ought to be. 



S. "QdliaidiXd. (Palmafedeaved S.) — This beautiful species is one 

 of the finest of hardy herbaceous plants. It is of recent intro- 

 duction. It is similar in style of leaves, habit, and inflorescence 

 to the last, but is superior to it in effect of colour, which is 

 deep crimson, of which the stems also partake a considerable 

 length downwards. The flowers appear the same time as the last.
