APPENDIX

BRITISH PLANTS CULTIVATED FOR ORNAMENTAL PURPOSES.

1. 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.

4. ANTHEMIS maritima. A double-flowering variety of this plant used to
be common in the gardens near London, but is now scarce: it is very
beautiful, and constantly in bloom during summer. It is propagated by
planting the roots in the spring and autumn.

5. ANTIRRHINUM linaria, v. Peloria.--I cannot pass over this singular
and beautiful flower without notice. There is a fine figure of it in the
Flora Londinensis: it is very ornamental, and the structure of the bloom
is truly interesting. It is easily propagated by planting the
