Rose Family 351 



arching bush (three to four feet), like snow, before the appearance of 

 the small leaves; the feathery, bright green foliage in graceful sprays 

 turning to golden bronze. It is most ht for rounding off groups of 

 shrubbery. 



S. argula, a garden variety of the former and similar to it, excels in 

 its more vigorous development, earlier and more profuse, feathery, 

 pure white, larger flowers, and in its perfect hardiness. 



S. prunifolia Jlore plena S. & Z. (ii6), Bridal-Wreath, the double- 

 flowering, plum-leaved Spircea, is only half hardy at Ottawa, a taller 

 shrub (live to seven feet), with arching branches, beset with tiny white 

 double flowers in early spring before the appearance of the leaves, which 

 are glossy green, turning brilliant orange. 



S. sorbifolia Linn. {Sorbaria sorbifolia A. Braun), from the Ural to 

 Japan, is one of the tallest Spiraeas (ten feet), with large pinnate elegant 

 foliage, and long terminal tassels of pure white, late flowers (June, 



July). 



S. trilobata Linn. (117), only two to four feet high, with similar 

 wealth of flowers in May; but more striking on account of size and 

 pinkish color. 



* 5. Van Houttei Zabel. (118), the most profuse, hardy bloomer, 

 covering the gracefully spreading branches from end to end (four to 

 six feet), with blossoms in dense umbels in May. A smooth, trifoliate, 

 dark green foliage, with pale underside and rounded form, adds to its 

 usefulness for border planting. 



S. bracteata Zabel {media rotundifolia) , a garden variety, comes next 

 to the foregoing in time, with its showy umbels of white flowers, and 

 excels in its fine, red-brown color of twigs, and dark green handsome 

 foliage, remaining fresh until late in fall. 



Of the pink-flowering ones, three recommend themselves: 



S. Bumalda Burv. (119), the Everblooming Spircea, a flat- topped but 

 upright dwarf, with a profusion of rose-pink flowers (throughout sum- 

 mer and fall), with serrate foliage, of rare beauty; 



S. Anthony Waterer (iiga), a variety of the former, with larger, 

 pink to crimson flower heads (July, August), which continue through- 

 out the summer. 



5. superba Zabel (iigb), a low shrub with striped dark brown 

 branches, large leaves, and light pink, rather large flowers (June, 



July).
