Seasonal gift of English flower and European goods (6,3)
I believe the answer is:
easter egg
'seasonal gift' is the definition.
(gift given at Easter)
'english flower and european goods' is the wordplay.
'english' becomes 'e' (abbreviation).
'flower' becomes 'aster' (type of flower).
'and' is a charade indicator (letters next to each other).
'european' becomes 'E' (abbreviation e.g. EU).
'goods' becomes 'gg' (g is abbreviation for good - twice).
'e'+'aster'+'e'+'gg'='EASTER EGG'
'of' is the link.
(Other definitions for easter egg that I've seen before include "festival food" , "Springtime confection" , "DVD feature?" , "Programmer's surprise" , "Seasonal fare" .)
