didly, and though these plants do not give us so much blossom
in unfavourable positions, still they make a very pretty show.
_Aubrietias_ can be easily propagated by division; every morsel grows.

=BANKS UNDER TREES.= The white _arabis_ also does well under similar
conditions; both are useful for draping perpendicular surfaces, such as
the steep side of a bank or hedge. A raised border, with facing of bricks,
is rather a nice way of growing plants under trees, and the work of
tending them is pleasant, less stooping being required.

The =mossy saxifrage= droops over the edges, and mingles well with the
_arabis_, but it must be more carefully watered, as it is apt to die out;
pieces should constantly be taken off, and dibbled in so as to fill up any
gaps. The =periwinkles= meander charmingly over the roughest stones, and
in the most dreary spots; their glossy ever-green leaves, and fresh bright
little flowerets =always looking cheerful= whatever the weather. They
creep quickly, rooting every few inches as they grow; on the perpendicular
face of the rock, succulent plants like =echeverias= can sometimes be made
to grow (those little green rosettes, having each leaf tipped with red,
which can be bought so readily in May for about twopence each).

=Many things will do for a time=, that want renewing each year, even if
hardy. Cowslips, primroses, polyanthus, wallflowers, all will make a fair
show if planted out just before flowering, but, unless a few hours' sun
daily shines on them, they will not retain enough vitality to produce
seed, and being biennial soon die out, leaving not a trace behind.

=A great many bulbs do admirably under deciduous trees=, especially those
which blossom before the new leaves on the branches above them have
reached any appreciable size.

=Scillas= bloom in the same place year after year; snowdrops also do
fairly well, and lilies of the valley ring out a few of their dainty
bells every spring (a rich vegetable soil suits them best). =Tulips= only
do well when planted afresh every autumn; but, as they are so cheap, that
is not a great matter. The _megaseas_, mentioned in another chapter, give
forth many of their fine leaves, but they refuse to turn colour, owing to
the want of sun. Fox-gloves, also, grow and flower, seeming to enjoy their
position.

=If the aspect of the space to be filled is a cold one=, such things as
geraniums will only give a few poor flowers, and then succumb. Even
