Viscountess Frances Garnet Wolseley, Gardening for women (1908)
“ These stones and the lower portion of the pots are partially hidden by groups of irises, pæonies, aquilegias and roses, growing in the border. Just a touch of the terra-cotta flowerpot with its handsome ornamentation of wreaths, is seen above the blue and white of the irises or the many-coloured ranunculuses, and then, above, high up, we get the foliage and colour of the shrub which is planted in the pot. It is certainly a most effective way of giving height and variety to a flat, rather uninteresting piece of ground. ”
