Kill weed accidentally? It's edible (4,4)

I believe the answer is:

wild leek

'it's edible' is the definition.
(type of edible plant)

'kill weed accidentally?' is the wordplay.
'accidentally?' indicates an anagram (I've seen 'accidentally' mean this (a chaotic or accidental ordering of the letters)).
'kill'+'weed'='killweed'
'killweed' with letters rearranged gives 'WILD LEEK'.

I've seen this clue in The Guardian.
