Sedum hispanicum is a decorative, low-growing, perennial succulent plant that grows up to 15 cm (6 inches) tall. It has blue-green, succulent foliage. As the weather warms, the foliage turns to a blue-grey colour and it has a soft feathery feel to it. In late spring to summer it has clusters of small, whitish-pink blooms.
