Odd bits of your cocoa plant (5)
I believe the answer is:
yucca
'plant' is the definition.
'odd bits of your cocoa' is the wordplay.
'odd bits of' means one should take alternating letters.
'your'+'cocoa'='yourcocoa'
The alternating letters of 'yourcocoa' are 'YUCCA'.
(Other definitions for yucca that I've seen before include "Evergreen N American shrub" , "Tropical lily genus" , "Common indoor plant" , "houseplant" , "Garden plant from Mexico" .)
