(Chinese windmill palm, Chusan palm)
One of the hardiest palms, Chinese windmill palm has single stems with large, 4-foot-wide fans of sword-like leaves. It produces large plumes of yellow flowers in early summer; the flowers of female plants transform into bluish-black fruits. Chinese windmill palms may be shoot-hardy to Zone 6 if protected with 10 inches of mulch. With their rich fans and handsome habits, they make attractive specimens for formal outdoor spaces. These evergreen palms are native to the mountains and temperate regions of subtropical Asia. Plants can grow to 20 feet tall and 8 feet wide.
