A beautiful majestic tree that I long to be able to grow to maturity but in our climate it is at best a potted plant. Often used as potted Christmas trees they often fail because of the lack of humidity in our central heated homes.

Cultivation
Easy to grow in the proper climate in well drained soil but commonly grown in North America as a potted house plant.

Place the plant on a saucer of gravel and fill with water, mist the plant periodically and keep it away from any direct heat sources.
