The colour is a fine, vivid green,
and provides refreshing brightness to the dark
corners of the garden. Other ferns suited
to the ' wet' garden are the Hardy Maidenhair
Fern with black stems and pale green fronds,
the Buckler or Hay-scented Ferns, and the
Lady Fern growing to three feet in height and
a very striking lady indeed.
The foregoing ferns are what one might
call the ' background,' but there is one fern,
growing to a bare nine inches in height, that
makes a fine green carpet and looks particularly well under trees ; this fern is Polypodium
plumosum.
The flowering bog plants, perhaps from their
very seclusion, have, as a rule, prolific and
brightly coloured blooms. One of the finest
bog gardens that I have seen had, as its main
feature, a mass, some fifteen feet square, of
Primula japonica (Japanese Primrose). The
blooms of this particular primula are at the
end of stems some two feet long-the leaves
are clustered around the base-and in this
garden the scarlet blooms were all about the
same height from the ground. The effect
was, in the shadows, most enchanting. There
are about twenty other species and varieties
of primula suitable for the bog garden and
each has its own characteristic mode of growth ;
the colours may be white, yellow, orange, red
or purple.
These and the Iris kind (there are over 50
different Irises from which to choose) are the
backbone of this particular type of garden ;
at their feet, as it were, are the smaller plants,
gorgeous in colour and prolific in growth.
There are the Arum Lilies and the
Marigolds ; Fairies' Wands (Galax), dainty
plants with spikes of white flowers, the golden-
flowered Lysichitum, delightful Wood-lilies
(Trillium) with their large purple flowers ;
Veronica gentianoides that has such beautiful
lilac flowers growing in dense carpets and that
like the sun ; Solomon's Seal and the similar,
though smaller, Bell Wort, the drooping flowers
of which are yellow ; these and many other
plants can be grown in the bog garden.
Also
there are several small bog-loving flowering
shrubs that are very attractive, the Bog
Rosemary for instance, and Cowberry,
Spiraea, Sweet Pepper Bush and several
others.
Before leaving the entrancing bog garden,
I would like to point out that a little sunshine
is welcomed even by the ferns ; so, if it can
be managed, it should be situated so that for
an hour or thereabouts each day the direct
rays of the sun can play upon it. This will
prevent the soil from becoming sour and the
plants will appreciate it too.
