Calathea medallions are upright foliage plants that readily fill out into broad, rounded rosettes. At maturity, the species typically reach between 24" to 36" tall if supported by a cane or cactus stake. Otherwise, calathea medallions will become bare-bottomed bushes without adequate support. This occurs as the creeping stems grow until they touch the soil and root there to form new plants. And, this is a wonderful way to propagate them! Calatheas have succulent rhizomes that form the thick "cushion" of leaves around their bases from which multiple shoots rise. The upper surface of each leaf is frequently dark green with white or cream stripes. The leaves are often described as "marbled" or "agouti."
