It is an evergreen tree that can grow 30-70 feet tall, with brown main shoots bearing whorls of 4-7 inch long flexible green cladodes that look like, and perform the function of, leaves but are actually composed of stem tissues; occasionally, a cladode will be forked and produce a bud in the 'v' of the fork. The cones are 3 - 7 inches long, mature in about 18 months, and have flattish scales that open to release the seeds. It is a very attractive tree and is popular in gardens, despite its slow growth rate and high cost.
