Has laid out flowers in the garden (7)
I believe the answer is:
dahlias
'flowers in the garden' is the definition.
'dahlias' can be an answer for 'flowers' (dahlia is a kind of flower). I'm not sure about the 'in the garden' bit.
'has laid out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'has'+'laid'='haslaid'
'haslaid' with letters rearranged gives 'DAHLIAS'.
Can you help me to learn more?
(Other definitions for dahlias that I've seen before include "I had Al's fowers" , "Tuberous Mexican flowers" , "Herbaceous perennial plants of a Mexican genus" , "'Hid, alas, among the flowers (7)'" , "Might Ali dash for the flowers?" .)
