Plant that’s difficult gardener is going to put in fine soil, initially (9)
I believe the answer is:
amaryllis
'plant' is the definition.
The answer is an example.
'difficult gardener is going to put in fine soil initially' is the wordplay.
I cannot quite see how this works, but
'is' is found in the answer.
'going to' could be 'll' (as in he'll, we'll etc) and 'll' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'that's' is the link.
Can you help me to learn more?
(Other definitions for amaryllis that I've seen before include "Sly alarm I turn on for the flower" , "Trumpet-flowered bulb" , "Large-flowered bulb" , "Bulbous plant with trumpet-shaped flowers" , "Lily-like plant" .)
