Frond plant (4)
I believe the answer is:
fern
'frond plant' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for fern that I've seen before include "Leafy plant" , "Plant such as bracken" , "Plant reproducing by spores" , "Flowerless plant with feathery fronds" , "It has feathery or leafy fronds" .)
