Wilkesia gymnoxiphium (Hawaiian iliau), is a species of flowering plant in the family Asteraceae that is endemic to the island of Kauaʻi in Hawaiʻi. It is classified as endangered on the IUCN Red List. Wilkesia is one of three genera, with Argyroxiphium (silverswords and greenswords) and Dubautia (a larger group with many varied species) that are believed to be descendant from a single species related to the North American tarweed. The members of these three genera constitute what is called the silversword alliance, a group whose exceedingly close genetic heritage is not reflected in their exceptionally diverse morphologies.
How to keep Wilkesia Gymnoxiphium.
Pruning
Iliau thrives with minimal pruning, which is best done in early spring to remove any dead or diseased leaves. Trim any faded flowering stalks to help redirect the plant's energy. Be careful not to over-prune, as this can disrupt its natural shape. By limiting pruning, you promote healthier growth and enhance the plant’s visual appeal in gardens.
