Cyathea cooperi (Australian Tree Fern)
Australian Tree Fern, Cooper's Tree Fern, Lacy Tree Fern, Scaly Tree Fern, Alsophila cooperi
Fast-growing, award-winning Cyathea cooperi (Australian Tree Fern) is an evergreen tree fern with a very attractive terminal rosette of gracefully arching, lacy, emerald-green fronds, up to 13 ft. long (4 m). The new fronds or 'fiddleheads' are particularly beautiful, curled up with a delicate covering of silky hairs. The undersides of the mature fronds are covered with dusty brown sori aligned in rows. The slender, pale trunk is patterned with contiguous oval scars from older fronds. Incredibly easy to grow, Australian Tree Fern thrives where there are mild winter temperatures, dappled sunlight and plenty of moisture. It has a strong architectural presence and makes a spectacular accent in gardens where winter hardy, and in containers.
- Winner of the prestigious Award of Garden Merit of the Royal Horticultural Society
- Grows with an upright habit up to 15-20 ft. tall (450-600 cm) and 10-12 ft. wide (300-360 cm).
