Bog And Tub Gardens
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.
