Mosaic a cabinetmaker put up featuring plant (6)
I believe the answer is:
acacia
'plant' is the definition.
(acacia is a kind of plant)
'mosaic a cabinetmaker put up featuring' is the wordplay.
'featuring' indicates the answer is hidden within the clue.
'put up' shows that the letters should be reversed in order.
'aicaca' can be found hidden inside 'mosaic a cabinetmaker'.
'aicaca' written backwards gives 'ACACIA'.
(Other definitions for acacia that I've seen before include "Shrub of warm climates" , "Gum-yielding tree ir shrub" , "(Sub)tropical shrub with yellow or white flowers - wattle" , "Spiny tree of warm climates" , "Spiny shrub with clusters of yellow or white flowers" .)
