Funny hue by red borders of reseda plant genus (8)

I believe the answer is:

heuchera

'plant genus' is the definition.

'funny hue by red borders of reseda' is the wordplay.
'funny' indicates an anagram.
'by' is a charade indicator (letters next to each other).
'red' becomes 'che' (Che Guevara the Marxist revolutionary).
'borders of' suggests removing the centre.
'reseda' with its middle removed is 'ra'.
'hue' anagrammed gives 'heu'.
'heu'+'che'+'ra'='HEUCHERA'

(Another definition for heuchera that I've seen is " saxifrage".)

I've seen this clue in The Guardian.
