Enraptured dad turns up among a variety of orchids (9)
I believe the answer is:
rhapsodic
'enraptured' is the definition.
(I know that enraptured can be written as rhapsodic)
'dad turns up among a variety of orchids' is the wordplay.
'dad' becomes 'pa' (both can mean one's father).
'turns up' says the letters should be written backwards.
'among' is an insertion indicator (inserted letters are placed among others).
'a variety of' is an anagram indicator.
'pa' written backwards gives 'ap'.
'orchids' with letters rearranged gives 'rhsodic'.
'ap' going inside 'rhsodic' is 'RHAPSODIC'.
(Other definitions for rhapsodic that I've seen before include "of utter delight" , "Wildly emotional" , "Ecstatic, extravagantly enthusiastic" , "Freely emotional" , "Expressing delight" .)
