Windmill Palm fruit as it opens (this was 3 days after the above photograph was taken)
Male and female flowers are borne on separate plants (so this palm is said to be dioecious). They are densely arranged on 2-3 ft (0.6-0.9 m) long branched stalks called an inflorescence. The windmill palm's bright yellow inflorescence erupts from a packet-like bud in late winter and early spring and is held within the crown. On female plants the flowers are followed in late summer by round or oblong blue fruits that are about 1/2 in (1.3 cm) in diameter. Mine bears the yellow flowers but has never fruited, so I presume it is a male. In older individuals the fibers on the trunk sloughs away to reveal a smooth ringed surface. The Windmill palm is one of the most cold hardy palms available. It is beautifully compact and grows to heights of 20-40 ft (6.1-12.2 m) so no wonder it survived our very frosty winters here in Tarlton!
