They are green when young but turn brown and papery as they mature. The fertile fronds will actually vary in appearance according to the light intensity they are grown under. This can result in members of the same species that appear to be completely different. Reproduces by producing spores that are blown off the fronds and spread by wind to other trees. Best grown in greenhouses or outdoors in suitable climates, but can be grown as house plants with attention to care.
Filtered sunlight is best.
Avoid direct, hot sun. These plants often grow in trees where light is filtered by the leaves and branches of the tree. Spraying leaves directly can result in leaf spotting. Potted plants should be watered when the soil is dry. Take care not to over-water which can cause fungal rot and death.
