Plants freshly cut in containers (8)
I believe the answer is:
cactuses
'plants' is the definition.
The answer is an example.
'freshly cut in containers' is the wordplay.
'freshly' indicates anagramming the letters.
'in' indicates putting letters inside.
'containers' becomes 'cases' (case is a kind of container).
'cut' with letters rearranged gives 'ctu'.
'ctu' placed into 'cases' is 'CACTUSES'.
(Other definitions for cactuses that I've seen before include "plants with bright flowers" , "Spiky desert plants" .)
