Appropriate planting kiss on Queen? (5)

I believe the answer is:

annex

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

'appropriate planting' is the definition.
'annex' can be an answer for 'appropriate' (annexing is a kind of appropriating). I'm not sure about the 'planting' bit.

'kiss on queen?' is the wordplay.
'kiss' becomes 'x'.
'on' says to put letters next to each other.
'queen?' becomes 'anne' (I've seen this before).
'x' after 'anne' is 'ANNEX'.

Can you help me to learn more?

(Other definitions for annex that I've seen before include "Attach (land)" , "Take (land) by conquest" , "An addition that extends a main building" , "Add to one's territory" , "Add by conquest or occupation" .)

I've seen this clue in The Telegraph.
