Are staghorn ferns a vegan alternative to mounted taxidermy? According to our guest, they are! Platycerium ferns are known for their coarsely branched fronds that resemble antlers more than the delicate, airy foliage of other ferns. They have certain cultural requirements for success, but these are fantastic as houseplants and one of the best ferns for indoor success. The Plant Daddies bring a friend on the show to teach him how to mount (“with ruthless efficiency”) and care for these botanical oddities.
