Cass Robusta - This fern is characterized by its deeply divided and wide fertile fronds with distinctive long narrow fingers.

This particular fern is from the Tony Barrett collection.

This staghorn fern can take temperatures from 40 to 90 degrees - they are kept outside year long and prefers morning light or a dappled light all day with a mild breeze.

The mounting medium is AAA New Zealand Sphagnum Moss and then the fern is attached to redwood boards with 40lb monofilament fishing line, garden tape or other strapping material. When fertilizing - I use either Miracle-Gro or Superthrive every 3rd or 4th watering. While most of the mountings seem larger than necessary, this fern will cover the boards in 3 to 4 years.

There are various sizes of Cass Robusta that are currently available for sale. If interested please e-mail me at
