The spikey chartreuse foliage looks like it would be tough and prickly, but is actually quite soft and "petable." It is wonderful in landscapes and is an outstanding container plant, where it will fall over the edge of containers. It loves heat and can tolerate dry soils, although average moisture will keep it looking fresh. Lemon Coral is grown for its lovely foliage, although if you are lucky it may bloom as well.
