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 fit for rounding ol_.roups of 
shrubbery. 
S. arguia, 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. pruntfolia flore pleno S. & Z. (116), Bridal-Wreath, the double- 
flowering, plum-leaved Spirea, is only half hardy at Ottawa, a taller 
shrub (five 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 Spireeas (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. . 
* S. Van Houitet 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. (x19), the Everblooming Spirea, 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. Anthon. Waterer (119), a variety of the former, with larger, 
pink to crimson flower heads (July, August), which continue through- 
out the summer. 
S. superba Zabel (119d), a low shrub with striped dark brown 
branches, large leaves, and light pink, rather large flowers (June, 
July).
