Tulip surprisingly bright in display? (3,2)
I believe the answer is:
lit up
'bright in display?' is the definition.
'tulip surprisingly' is the wordplay.
'surprisingly' is an anagram indicator.
'tulip' anagrammed gives 'LIT UP'.
(Other definitions for lit up that I've seen before include "high" , "Drunk (as a bulb?)" , "Flashing" , "Illuminated (by drink or drugs?)" , "was illuminating" .)
