Plant seeds while ignoring hard ground (9)
I believe the answer is:
edelweiss
'plant' is the definition.
The answer is an example.
'seeds while ignoring hard ground' is the wordplay.
'ignoring' suggests deleting specific letters.
'hard' becomes 'h'.
'ground' indicates anagramming the letters (grind the letters ).
'seeds'+'while'='seedswhile'
'seedswhile' with 'h' removed is 'seedswile'.
'seedswile' with letters rearranged gives 'EDELWEISS'.
(Other definitions for edelweiss that I've seen before include "flower as national symbol" , "Alpine plant, celebrated in song" , "White-flowered alpine plant" , "Deep admiration" , "Ewe slides on the alpine plant" .)
