One may be in bed, commando, under cover (reportedly) (9)
I believe the answer is:
hydrangea
'one may' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'be in bed commando under cover reportedly' is the wordplay.
I cannot quite understand how this works, but
'be' could be 'range' (ranging is a kind of being) and 'range' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for hydrangea that I've seen before include "Flowering plant - angry head (anag)" , "Shrub of the saxifrage family -- angry head (anag)" , "Common garden plant" , "Ornamental flowering shrub - handy gear (anag)" , "Garden flower - garden hay (anag)" .)
