I am in Florida and my growing zone is 9a but we did get an ice storm this past winter. A few years ago I bought a tree fern and I kept it potted for a while then I planted it. The winter came and it died. I thought that the Australian tree fern would be tough enough to survive here but I guess not although who knows maybe it didn't get established enough before the cold hit. Anyways, is there a good hardy alternative to the tree fern that anyone knows about? I am mainly interested in the look of those big, feathery, fern leaves. I was watching Treehouse Masters recently and saw that one lady's yard had huge ferns that looked like tree ferns but they were just regular ferns. I liked the look of those. So is there any kind of giant fern that is hardy? I figure it might die back in winter and come back in the Spring which is fine as long as it comes back! Tree ferns are just one of those plants I really want...Someday I would like to have a big greenhouse so that I can have tree ferns and other tropical plants that don't do well in our winters.
