Raphia have the longest leaves of any plant, those of R. australis measuring
up to 18m (60 ft)! It is very fast growing, among the fastest of all palms,
and requires an abundance of water to support that growth, preferring
swampy areas. The leaf bases and petioles are a bright orange, and, together
with the stiffly ascending leaves, this presents a once-seen-never-forgotten
sight. Understandably, it requires a lot of space to be seen fully, but
in a park or a large garden, it is spectacular!
