I weed less clumsily, seeing Alpine plant (9)
I believe the answer is:
edelweiss
'alpine plant' is the definition.
(I've seen this before)
'i weed less clumsily' is the wordplay.
'clumsily' indicates an anagram.
'i'+'weed'+'less'='iweedless'
'iweedless' anagrammed gives 'EDELWEISS'.
'seeing' is the link.
(Other definitions for edelweiss that I've seen before include "Ewe slides on the alpine plant" , "high growth" , "Alpine flower - "The Sound of Music" song" , "Swedes lie about small white flower in Switzerland" , "Deep admiration" .)
