Many dyckia cultivars have striking bronze, purple, or silver foliage that makes them especially attractive in contemporary garden designs. They can be planted en masse as a groundcover, or used individually to add an interesting element in a container garden.In the spring, the plants produce flower stalks that have dozens of small but showy flowers that are usually a vivid yellow or orange. The flower stalks can reach up to five feet tall, depending on the cultivar.Dyckia will naturally form a clump over time, as each plant produces young pups around it. Because of this growth habit, dyckia can be used as a groundcover.
