Isn't this gorgeous with its fat spring foliage? It should be planted in full sun and never irrigated. Thankfully, this plant is getting easier to find in general nurseries. All the native plant nurseries stock it.
Look how well the color matches Teucrium fruticans, a completely drought tolerant plant related to rosemary and beloved by bees. They look very good together in a silver garden. Teucrium grows quite large over the years and plenty of space should be allowed between these plants should you use them together.
