Hm, much as I dislike the idea of growing an invasive fern, this one has only appeared in one spot in my garden, and is quite small and well-behaved. If I see it propagating itself elsewhere in the garden I'll sure pull it out, but I really kind of like it where it is, growing out of the stones on the fake waterfall of my pond.
I wonder if it doesn't like the high pH well water that the rest of the garden is irrigated with, in the dry seasons (if we ever get a dry season again . . . ) If that's the case, well it's not going anywhere from where it's situated right now.
