Spiraeas

Placed in the open ground these make splendid plants, andare not particular as to soil, though a moist, rich one is preferable.
For forcing, plant the clumps in 6-in. pots, and keep them in a cool
frame until they are well rooted. They may then be removed indoors
and forced rapidly, supplying them with an abundance of water.
Their elegant flower spikes are invaluable for bouquets and table
decoration. The shrubby kinds are increased by layers or cuttings of
the young wood, the herbaceous varieties by division of the roots
in autumn. Spiraea Aruncus, if potted early in the autumn, is very
valuable for winter decoration. Spiraeas bloom at different periods,
from May to August, and vary in height, 3 or 4 ft. being the general
growth.
