Plant shoot died, one in meadow (8)
I believe the answer is:
buddleia
'plant' is the definition.
(buddleia is a kind of plant)
'shoot died one in meadow' is the wordplay.
'shoot' becomes 'bud' (I've seen this before**).
'died' becomes 'd'.
'one' becomes 'i' (Roman numeral).
'in' indicates putting letters inside.
'meadow' becomes 'lea' (I've seen this before).
'i' inserted within 'lea' is 'leia'.
'bud'+'d'+'leia'='BUDDLEIA'
(Other definitions for buddleia that I've seen before include "Fragrant shrub attractive to butterflies" , "Ornamental plant" , "Flowering shrub" , "Butterfly bush" , "flowering plant" .)
