ALISMA Plantago. I cannot pass over this beautiful aquatic without giving it a place amongst the ornamental plants with which our country abounds. In pieces of water this is of considerable interest both as to flowers and foliage, and no place of the kind should ever be destitute of such a beauty. It is of easy culture; the plant taken from its place of growth and sunk into the water with a stone to keep it in its place, is a ready and easy mode of planting it, and there is no fear when once introduced but it will succeed. 2. ANDROMEDA polifolia. This is a beautiful little shrub, and grown in gardens for the sake of its flowers; it is also an evergreen. This plant will not succeed unless it is planted in bog earth,--for a description of which see page 152 of this volume. 3. AQUILEGIA vulgaris. COLUMBINE.--We have scarcely a plant affording more beauty or greater variety than this. It is commonly, when found wild, of a blue colour, but when the seeds are sown in the garden a variety of tints is produced. It is a perennial, but easily raised from seed, which should be sown in the spring.
