Sphaeropteris cooperi

Australian tree fern.

Thank you so much for the ID. I wouldn't have been able to it myself.

Thats a beautiful fern! I had to google the name as the link wasn't parsing,probably due to the @ in the link.
Found some info on it.

Here is a link that might be useful: Sphaeropteris cooperi

Really Cyathea cooperi. About as fast growing and tough a tree fern in the world. Maybe not THE hardiest-but close and with all other traits surpass the others. Helps too it is easily propagated..a nurserymans dream tree fern!

Would this survive my winters? Wet and cold?

Mine survives typical winters in 8b - 9a. Keep it faily dry and provide good protection for the tip of the crown. Do not allow water into the crown during the winter. I slide a large cardboard bow over mine. Shovel it full of dry leaves, then cover the whole thing with a Big trashbag, but allow for some air circulation. I normally have to trim the fronds quite a bit. I start watering with high pottasium fertilizer in the fall, and cover it just before the first frost.
