Re: Sadleria cyatheoides

Hi Dean,
We grow a lot of ferns with fed fronds and there are quite a few local
native ferns here with emerging red fronds, mostly Blechnums.  We do find
the more nutrients we give them, the less red the foliage so soil conditions
may play a part during evolution.  We are told that our ferns have great
colour due to our cold and misty climate.  However we are only 400 metres
above sea level.  In my experience, a red fronded variety always puts out
red new fronds while a similar fern with green new fronds remains green.
The ferns grown from the respective plants remain true to their parents.
