A unique species with very original flowers: double, rosette like, creamy-white-green turning into greenish white in autumn. Blossoms only on the new wood, from June to September. As not fully hardy, it’s best grown in a wind sheltered position e.g. on a wall facing south. Thrives best in moist well drained soil. Good protection in winter is required. Best suited for cultivation in containers that are transferred in winter to a cold room with the temperature between 0^oC and 5^oC.
