I'm waiting on seeds from them too. I can't wait to get them. Another good cheap site is
Pinetree Seeds . I haven't tried them, but I have it on good authority that they're good.
I checked on Japanese Painted Ferns,
here is about the cheapest place I found. They also had your
Ostrich Fern . All the ferns are on sale for 50% off. How nice is that?
Actually, lol, here is the
real japanese fern , the other link is too a real cool hybrid of japanese fern ursala.
