Desert plant around Connecticut (America) (6)
I believe the answer is:
cactus
'desert plant' is the definition.
(I've seen this before)
'around connecticut america' is the wordplay.
'around' becomes 'ca' (circa).
'connecticut' becomes 'ct'.
'america' becomes 'us' (abbreviation for the United States).
'ca'+'ct'+'us'='CACTUS'
(Other definitions for cactus that I've seen before include "Eg, prickly pear" , "Spiny desert plant" , "Thorny desert plant" , "Prickly desert plant" , "Often prickly succulent plant native to arid regions" .)
