Adore getting to the bottom of cold Bud (5)
I believe the answer is:
clove
'bud' is the definition.
(I know that clove is a type of flower bud)
'adore getting to the bottom of cold' is the wordplay.
'adore' becomes 'love' (I've seen this in another clue).
'getting to the bottom of' is a charade indicator (letters next to each other).
'cold' becomes 'c' (eg on taps).
'love' after 'c' is 'CLOVE'.
(Other definitions for clove that I've seen before include "Garlic segment" , "Split; spice" , "Flower bud used as a spice" , "Payment for hostage" , "caused separation" .)
