We're looking at a houseplant here for everyone except those with that San Francisco microclimate and if you are lucky enough to have such a thing, just for the record - we pretty much hate you.  But we'll set aside the envy and sell you one of these astoundingly lovely ferns with long white ghostly fingered fronds.

This was one of those "Holy shit - lookit that fern!" moments when we first spotted this species growing at the base of soaring pinnacles of vertical peaks in Guizhou, China where it was not intimidated in the least and perfectly in scale.  Massive 4'-6' wide fronds 6'-8' tall in the wild and clumping.  Likely smaller in cultivation but still BIG!  Zone 7b-9.
