Exaltation and short satisfied expression for one in bed (8)
I believe the answer is:
larkspur
'bed' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for larkspur that I've seen before include "Delphinium-like plant" , "Flower like a delphinium" , "Mediterranean plant with spikes of blue, pink or white flowers" , "Blue flower" , "it grows" .)
