Seed-packed fruit (3)
I believe the answer is:
fig
'seed-packed fruit' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for fig that I've seen before include "Soft sweet fruit of broad-leaved tree" , "Fruit with lots of seeds" , "Tree whose leaf may cover nudity" , "Sweet fleshy fruit, often dried" , "Tree whose leaf may conceal nudity" .)
