Pronunciation: lih-KWAL-uh RAM-zee-eye

Common Name: Australian Fan Palm; Wedge-leaf Fan Palm

Licuala ramsayi is one of the easier Licualas to grow in California… but saying that does not make it an easy palm. Most Licualas are impossible to grow here, so this is an exception. But growing this plant well still requires protection from the elements, strict observance of water needs and a good microclimate. In its native Australia, this palm eventually grows into a tall forest of trees which can be walked beneath (unlike most Licualas that stay fairly small and are classified as understory palms). However, in California, no 'trees' exist yet and likely few, if any, will attain enough height to walk below their canopies. Two varieties are described in the literature, with one being the 'type' and the other var. tuckeri, differentiated by having little to no spines along the petioles (so obviously this might be the more popular variety). Leaves are nearly circular, split randomly and have an ornamental edge as if cut by a pinking shears. It is a highly ornamental species.
