Worm put out with leafy plant (9)
I believe the answer is:
mayflower
'plant' is the definition.
The answer is an example.
'worm put out with leafy' is the wordplay.
'put out with' is an anagram indicator.
'worm' anagrammed with 'leafy' gives 'MAYFLOWER'.
(Other definitions for mayflower that I've seen before include "Historic vessel" , "Hawthorn blossom, carrying the ..." , "bark used by settlers" , "Hawthorne mentioned" , "Pilgrims' vessel" .)
