Plant went up just below dump (6,4)
I believe the answer is:
desert rose
'below dump' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'plant went up' is the wordplay.
'plant' becomes 'desert' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'went up' becomes 'rose' (I've seen this in other clues).
'desert'+'rose'='DESERT ROSE'
'just' is the link.
Can you help me to learn more?
(Another definition for desert rose that I've seen is " succulent".)
