Cutting quite a figure in the garden? (7)

I believe the answer is:

topiary

I'm a little stuck... Click here to teach me more about this clue!

'the garden?' is the definition.
(topiary is a kind of garden)

I don't understand how the rest of the clue works.

(Other definitions for topiary that I've seen before include "Ornamental pruning" , "Shrub-clipping art" , "Shrub and bush trimming for artistic effect" , "Riot pay (anag.)" , "Clipping trees to shape" .)

I've seen this clue in The Globe and Mail.
