Fern Invasion
Hello friends. I often find that ferns appear out of nowhere growing as guests in my orchid pots... uninvited but not unwelcome. Bruce says the same happens at his place. Does anyone else have the same experience? I am interested in how common (or uncommon) this is.
It further intrigues me that there are ferns whose spores are able to germinate AND their prothalli to develop and fertilise, AND the resulting juvenile sporophytes flourish... all in the harsh environment of the surface of orchid compost. These fern species must be very hardy and adaptable!
Here are a few examples... as you can see, the colonisation has spread from the orchids to the Dicksonia.
