The Rock Abelia (A. rupestris)

The Rock Abelia (A. rupestris) has been tried with satisfactory results for covering portions of a bare wall in the metropolis. It is a neat little shrub with slender shoots, shining green serrated leaves, and tubular sweet-scented flowers. Rich, well-drained soil is a necessity.

The Japanese Quince (Pyrus, or Cydonia japonica)

The Japanese Quince (Pyrus, or Cydonia japonica) is one of the most showy of wall plants, and can succeed well where smoke and dust abound. The flowers are brilliant crimson and produced in plenty towards the end of Winter and before the leaves appear. Wherever wall shrubs are being used in towns, this beautiful shrub should receive attention. It is of fairly rapid growth and would appear to do well in any situation.

Euonymus Japonicus

Euonymus Japonicus and the variety Aureo marginatus do well as wall shrubs in London-indeed, they succeed well where atmospheric impurities are known to exist. They make excellent wall plants and would seem to retain their foliage in better condition when used for this purpose than when planted as standards. These may be considered as the best of wall shrubs for town planting, but others have been tried with a fair amount of success - such as Buddleia variabilis, Ceanothus azureus, Coton-easter Sitnonsii, Indigofera Gerardiana, Aris-tolochia Sipho, Viburnum plicatum, but they are not to be recommended for very smoky localities.

The Hop (Humulus lupulus)

The Hop (Humulus lupulus) has few equals for covering a trellis or wall in smoky towns. Being an herbaceous plant of stout growth, it is well able to withstand both soot and smoke. The ample foliage and conspicuous fruit are additional recommendations.

The Large Trumpet Flower (Tecoma Radicans Major)

This old occupant of our gardens is perhaps the loveliest wall plant in cultivation, and having been found suitable for planting in towns is an extra qualification. The stems are long, twisted and wiry, while the graceful pinnate leaves and handsome trumpet-shaped, scarlet-red flowers all combine to make this wall shrub a general favourite with planters. It is quite hardy, of free growth, and flourishes best in a light, well-drained loamy soil. This well-marked variety, which differs from the species in its more robust growth, larger leaves, and paler flowers, is to be recommended for town gardening.

Wistaria Sinensis

Wistaria Sinensis has some claims to be considered as a town shrub, for numerous goodly specimens may be seen wherever the air is not too confined and impure. It is an excellent wall or arbour plant, the long drooping racemes of purplish-lilac flowers being produced in rich profusion. Not by any means difficult to cultivate, but, being a plant of wide spread, it should be allowed plenty of room for development.

The Brambles (Rubus)

The Brambles (Rubus) are likewise suitable for town planting, and two species at least have survived the ordeal of smoke, heat and dust for the past ten years in a city garden; R. laciniatus (the cut-leaved Bramble) would seem to be best suited for smoky localities.
