i got the fern name - can't find any pics of it on-line, but here it is: polypodium polycarpon 'filigree'. it's fantastic looking too. both of these plants are in private 'hybridization/propagation' section. this are plants in development so to speak, not for sale. there was nobody to ask, the place is huge. perhaps, i'll be more persevering next time. and if it was that easy to turn philo red - why wouldn't everybody do it? i don't think it's that simple of an answer. and it was the only plant of this kind. so i am reluctant to name a nursery. if i see it again, i'll take more and better pics and perhaps find smbody to talk too.
have you heard of this cultivar of fern before?
