Nice plants woven round centre of wreath (8)
I believe the answer is:
pleasant
'nice' is the definition.
('pleasant' can be similar in meaning to 'nice')
'plants woven round centre of wreath' is the wordplay.
'woven' indicates an anagram.
'round' is an insertion indicator.
'centre of' means to look at the middle letters.
The central letters of 'wreath' are 'ea'.
'plants' with letters rearranged gives 'plsant'.
'plsant' going around 'ea' is 'PLEASANT'.
(Other definitions for pleasant that I've seen before include "Charming" , "Attractive" , "Delightful" , "A greeable, affable" , "Enjoyable, nice" .)
