Genus Juania

Species in the genus Juania of plants

Juania australis - Juania australis is a solitary trunked palm tree which grows on the Juan Fernández Islands off the coast of Chile. This palm is slow growing and has a green trunk; plants are either male or female. It is extremely rare in cultivation and only one mature tree grows outside its natural habitat. Seeds from Juania australis are also banned from being exported from the Juan Fernández Islands by the Chilean government, for this reason seeds are virtually impossible to get hold of. It is also extremely hard to grow as it has very particular requirements, preferring cool night temperatures and summer temperatures below 25 °C , they are cold tolerant to about ?5 °C . It can grow successfully for years and then die for no apparent reason. It has been grown successfully in San Francisco, but two were lost there during a hot summer. There is a large 4 m specimen growing well at Earlscliffe in Dublin, Ireland, where the climate seems to suit this palm tree.
