Cycas thouarsii is one of the largest cycads and probably the fastest-growing, reaching over 30 feet tall, with a trunk up to 18 inches in diameter, producing offsets along its length. It generates up to 40 leaves at a time, each up to 10 feet long. Cycas thouarsii grows in open coastal forests of Madagascar, the Comoros Islands and the Seychelles. It is also found on the East Coast of Africa, where the species may have been established by Arab traders because of its beauty and food value.
This plant may be the oldest living Cycad, at an estimated 140 million years. It grows best in a moist, well-drained location, with light shade. During dry periods, it benefits from mulches and ample watering, and can handle temperatures down to 27 F.
