Digital assistant displaying flower in retreat (4)

I believe the answer is:

siri

'digital assistant' is the definition.
(assistant on Apple devices)

'flower in retreat' is the wordplay.
'flower' becomes 'iris' (iris is a type of flower).
'in retreat' says the letters should be written backwards.
'iris' reversed gives 'SIRI'.

'displaying' acts as a link.

(Another definition for siri that I've seen is " Apple's virtual assistant".)

I've seen this clue in The Everyman puzzle in The Observer.
