Comes to shore on promontory for creative sort of gardening (9)
I believe the answer is:
landscape
'sort of gardening' is the definition.
'comes to shore on promontory' is the wordplay.
'comes to shore' becomes 'lands' (I've seen this in another clue).
'on' says to put letters next to each other.
'promontory' becomes 'cape' (both can mean a headland).
'lands'+'cape'='LANDSCAPE'
'for creative' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for landscape that I've seen before include "Type of painting" , "improve grounds" , "Picture showing countryside" , "(Painting of) scenery" , "Possible prospect" .)
