@NJBob, I do not know what is going on in my back yard. I have Japanese painted ferns coming up in pots that I left on the patio for the winter. Before I purchased the two godzilla last yr I only had one 20 yr old painted fern in the Hosta garden. I do not think that walked across the garden to the patio. I do have a lot of birds,
Today I counted 4 of them coming up in various pots. I wonder how this is happening.
There is a fern that I cannot identify coming up in the pot that I had a hardy Hibiscus in that did not come back but a fern is growing in that pot.
At the bottom of the sun garden in the back is a big patch of sensitive ferns. That is a fern I have never had. It is like a fern fairy hit my backyard and and dropped fern bombs.
