Contrary to its name, the Australian tree fern (Cyathea cooperi, also known as Sphaeropteris cooperi) is actually more tree than fern. Typically, when we think of ferns, we picture plants such as painted ferns (Athyrium niponicum), which achieve a mature height of just 18 inches. But in its native habitat of Australia, a tree fern can grow up to 25 feet or more. 

Characterized by lacy, feathery fronds, and a hair-like, scale-covered trunk, the fast-growing Australian tree fern can bring an exotic touch to any garden. It's best planted in the early spring and prefers warm temperatures and plentiful sunlight year-round.

Australian tree ferns thrive in mid-elevation tropical environments, where they can sometimes be found growing in great, prehistoric forests swathed in tepid mist. The key to growing a healthy Australian tree fern is to provide it with ample humidity and consistency. Additionally, these plants are tolerant of salty winds near coastlines, but not salty soil conditions.

The trunk of the Australian tree fern starts out as a low, wide clump and spreads as much as six feet in a year before growing upward into a single slender trunk covered in glossy, ginger-brown hairs. The fronds are broad, bright green with triangular lacy leaves; they do not change color in the fall, and there are no flowers or fruit.

Light: Although Australian tree ferns are shade-loving plants in general, they can also thrive in partial sun or full sun locations where they get over six hours of light a day. Keep in mind, the more direct light the plant receives, the more likely it is that you'll need to increase your watering cadence. 

Watering: Keep the soil moist at all times. Australian tree ferns are not drought-tolerant and need weekly watering, with especially high levels of moisture or humidity in dry weather. Avoid watering the crown directly as this can cause rot—instead, water the trunk and ensure it's consistently moist.
