| Botanical Name | Cyathea cooperi (syn. Sphaeropteris cooperi) |
| Description | A fast-growing architectural marvel, the Australian Tree Fern creates a lush, tropical canopy in the Houston metro area. It absolutely thrives in our signature humidity but requires protection from the intense afternoon sun. While it enjoys consistent moisture, it is prone to root rot in heavy, water-logged soils. To succeed in Houston, plant it in a site with rich organic matter and ensure the soil is well-draining; it will not tolerate sitting in boggy clay. |
| Exposure | Filtered Sun to Part Shade (Protect from direct midday sun) |
| Height x Width | 15-30 ft. Tall x 8-12 ft. Wide |
| Water | High; keep soil consistently moist and water the trunk during periods of low humidity. |
| Zones | 9 - 11 (Requires protection during Houston freezes) |
| Fertilization | Apply a balanced, slow-release fertilizer at half strength during the spring and summer growing season. |
| Pruning | Remove brown or dead fronds as they age to maintain a clean appearance. |
| Deer Resistance | High |
