Cyathea cooperi, also known as Sphaeropteris cooperi, is very common, widely used, and fast-growing tree fern that can reach 49′ in height. It features a beautiful crown that spreads widely from the center and fronds can reach 13–20′ wide. New fronds, called crosiers, unfurl from the trunk center with long, straw-colored scales. It’s a hardy fern that’s easy to grow and prefers protected, shady, and moist conditions with some sun. In too much sun, it may not perform that well.
