Something for sale -- American plant (5)

I believe the answer is:

lotus

'plant' is the definition.

'something for sale american' is the wordplay.
'something for sale' becomes 'lot' (something for sale in an auction).
'american' becomes 'us' (abbreviation for United States).
'lot'+'us'='LOTUS'

(Other definitions for lotus that I've seen before include "Flower causing forgetfulness - cross-legged position" , "In myth, a plant whose fruit induced forgetfulness" , "Sacred waterlily" , "Sacred flower" , "----- Eaters, indolent hedonists" .)
