The foot of the wall will be best if it is not planted closely all along, but if occasionally some handsome warmth-loving plant is there in a tuft or group. Some of the plants most suitable for this place will be Acanthus, Iris stylosa, Crinums and Plumbago Larpenta; and of smaller plants, Anomatheca cruenta, Anemone fulgens y and in the south, Amaryllis Belladonna, Pancratium illyricuntj and Zephyranthes carinata. An occasional bush at the wall-foot would also come well, such as Rosemary, Cistus lusitantcus, Veronica hulkeana, Ozothamnus rosmarinifolius, or Griselinia littoralis. -- Gertrude Jekyll
This is an idea that may work very well for me. I had the notion to put Crinums, plumbago and Rosemary in the rose garden. They may be equally effective in front of the rock wall.
All the pinks shown here are dead, perished in the heat of summer. I'm thinking nasturtiums for spring, or California poppies. Fortunately the pinks are not a total loss. Young plants rooted early last summer are thriving elsewhere.
Some of your selections are unfamiliar; Anomatheca cruenta translates as freesias in my garden. I have several along a pathway. .
