Handy gear used in plant (9)
I believe the answer is:
hydrangea
'in plant' is the definition.
'hydrangea' can be an answer for 'plant' (I've seen this before). I am not certain of the 'in' bit.
'handy gear used' is the wordplay.
'used' indicates an anagram.
'handy'+'gear'='handygear'
'handygear' with letters rearranged gives 'HYDRANGEA'.
Can you help me to learn more?
(Other definitions for hydrangea that I've seen before include "Garden flower - garden hay (anag)" , "Shrubby plant with showy flowers" , "Showy flower" , "Plant's" , "Ornamental flowering shrub - handy gear (anag)" .)
