Shares the plants (6)
I believe the answer is:
stocks
I believe this clue is a double definition.
'shares' is the first definition.
(I've seen this before)
'plants' is the second definition.
(stock is a kind of plant)
'the' is the link.
(Other definitions for stocks that I've seen before include "Amounts of goods kept by traders" , "In which miscreant is locked" , "Capital holdings often accompanied by shares" , "Securities, investments" , "Supplies of goods in store" .)
