Dicksonia sellowiana, known as xaxim or imperial samambaiaçu, is a tree fern that can grow over 10 metres tall, native to subtropical and tropical forests of South America. Its dense, fibrous trunk (caudex) is harvested illegally, which puts wild populations at risk, so grow it from nursery-raised plants rather than wild-collected ones.
