e almost as hardy as the
common stock; it is most commonly however kept in the green-house.

The usual way of propagating this species, which is of ready and quick
growth, is by cuttings, which should be put into the ground as soon as
the plant has done flowering; these if properly treated will become
handsome plants to place in the green-house at the approach of Winter,
and to decorate it the ensuing Spring; in like manner may the
green-house be annually recruited with many similar plants to great
advantage.

The term _grandifolia_ would have been more applicable to this species
of Saxifrage than _crassifolia_, for it is not so much distinguished for
the thickness as the largeness of its leaves; these are almost equal in
size to those of our broad-leaved Dock, red on the under and of a fine
shining green on their upper surface; they may be ranked indeed among
the more handsome kinds of foliage; the flowering stems, according to
the richness and moisture of the soil in which they are planted, rise
from one to two or even three feet high; at top supporting a large bunch
of purple pendulous flowers, which blossom in April and May, and, if the
season prove favourable, make a fine appearance. Should cold winds
prevail at the time of their flowering, which they are very apt to do,
the plants should be covered with a hand-glass; or, if in a pot, it may
be removed into the green-house, which they will not disgrace.

Is found spontaneously on the Alps of Siberia, and, according to Mr.
AITON, was introduced in 1765 by Dr. SOLANDER. No plant is more readily
increased by parting its roots, which may be done either in spring or
autumn.

There is another Saxifrage in our gardens exceedingly like this in
appearance, but differing, in producing larger bunches of flowers, and
in having larger, rounder, and more heart-shaped leaves; Mr. AITON
regards this as a variety of the _crassif
