Dioon spinulosum

In nature, this extraordinary cycad can grow to 16m (50 feet) tall, making it one of the tallest cycads. In cultivation it is easily germinated, easy to care for, and fast growing. It is an attractive species with a regular crown of long, shiny green leaves with wide segments. It provides a very exotic but nevertheless formal touch in any garden in a warm temperate or tropical climate, and also makes a perfect pot plant for the conservatory or terrace.
