hey are apt to get lost in a mixed border. _C.
neapolitanum_ has marbled foliage and pretty pink flowers, and _C.
europeum_ (maroonish crimson) is also well worth growing; they must be
placed in a shady part, yet where the drainage is perfect; stagnant
moisture kills them.

The =hardy orchids= should be tried too, especially the _cypripedium_; it
is not generally known how handsome some of them are; they like shade and
moisture; indeed, through the summer the peat they are growing in should
be a regular swamp, or they will fail to produce fine flowers.

Another plant that likes peat is the little _daphne eneorum_. This is =an
evergreen=, and produces its pink fragrant flowers every spring; it will
not do in very smoky places, but, like the heath, must have a fairly pure
atmosphere.

=The alpine pinks are treasures for the rockery=, and do well in town
gardens; they flower nearly all the summer, and are not particular as to
soil and position, though they prefer plenty of sun.

=The gentians= look very well on rockwork, but like a stronger soil than
most alpines, loam suiting them best. Water should be generously given
during spring and summer. _G. acaulis_ is the best for amateurs.

The red shades found in the =geum tribe= are very uncommon, being neither
crimson, scarlet, nor orange, but a mixture of all three, with a dash of
brown thrown in. They =flower continuously=, and have dull green woolly
foliage, which sets the flowers off well. They need a light, well-drained
soil. _Geum chilense_, or _coccineum plenum_, is a good kind, and so is
_G. miniatum_; both are about two feet high, but require no staking
whatever. Of course, it will be understood that sticks, except of the
lightest kind, are =quite inadmissible= on a rockery.

=Helianthemums=, or =rock roses=, are charming little evergreen plants,
with wiry prostrate stems, and small flowers, which are freely produced
all the summer. They may be had in white, yellow, pink, scarlet, and
crimson, and either double or single; the variety named Mrs. C. W. Earle
is a very effective double scarlet, and quite a novelty.

=Iris reticulata= is =a very fascinating little bulbous plant=, well
adapted for a rockery; it blooms in the early spring, and very beautiful
the flowers are, being rich violet-purple, with gold blotches on each
petal; they are scented, too; when in blossom, the stems reach to about
nine inches in height.

One of the most lovely plants that can be im
