Donkey tail spurge
The Donkey-tail Spurge is a low growing, evergreen, succulent for crevices, walls or dry, alpine gardens.
It makes trailing stems, up to 30cm long, of grey-blue leaves, topped by clusters of chartreuse-yellow flowers in spring.
It will grow in almost any sunny area, but does particularly well in hot, dry sites with poor soil. Despite this tolerance for dry places, they require a little pampering to become established. It may need periodic watering during the summer. Water deeply, but don't let them sit in wet soil which can cause root rot. Once firmly anchored it becomes very low maintenance.
As with all the plants in this genus, the sap is toxic causing severe skin irritation and potentially anaphylactic shock. Always wear gloves and take precautions when handling.
