Archontophoenix alexandrae (Alexandra Palm)
Archontophoenix alexandrae is a tall palm, about 25 metres tall with a spread of about 2 meters. The leaves have a tendency to rotate 90 degrees to expose the whole leaf in profile, The base of the petioles form a bright breen crownshaft that the leaves rarely droop below. The trunk is smooth and ringed with noticible leaf scars and the base can be noticibly swollen. Flowers are creamy flower stalks holding amythest purple flowers. The round fruit turn bright red at maturity. They do like more water than most palms, with some even thriving in poorly drained areas. It is quite a fast grower, averaging about 1/3 - 1 meter per year.
