Alpine Rose - Notes

See Chapter 19.

Althaea - Notes

See Hibiscus.

A Melanchier - Notes

As stated in Chapter 9., A. canadensis (syn. Botryapium), is an attractive deciduous shrub and much the best of the genus. Apart from its flowers the autumn tint of the leaves must be considered in its favour. Florida is the same as alnifolia. Vulgaris is the common Amelanchier or Snowy Mespilus.

American Allspice - Notes

See Calycanthus. All have white flowers in spring.

American Arbor-Vitae - Notes

See Thuja, and Chapter 17. on Conifers.

Amorpha - Notes

Two species are generally offered: canescens, the Lead Plant; and fruticosa, the False Indigo. The former has blue and the latter purple flowers in late summer. The blossoms are Pea-shaped and produced in racemes. Height three to five feet. There are several varieties. The Amorphas are not thoroughly hardy and should have sheltered places.

Ampelopsis - Notes

The best plant by far grown under this name is Veitchii (syn. tricuspidata), which botanists now call Vitis inconstans. Its rapid growth, perfect climbing habit, neat foliage and beautiful colour in autumn render it one of the best of house plants for warm aspects. It is not particular as to soil. Nurserymen offer plants in pots suitable for planting at any time, but if the site is hot, planting should be done before the end of March, and it is wise to cut down the plants to within a foot of the base, and mulch with short manure. There is a dark form called purpurea. A. hederacea (syn. quinquaefolia), the common Virginian Creeper, is an altogether coarser plant, but it colours in the fall; muralis is a form of it.
