I have found out the name of a plant (thanks to you guys) that I want
to put in my garden, however, it seems that it might be classified as
a weed in some parts of the world. How do I go about finding out
information about these sort of classifications. I am in Adelaide
Australia.
Yes, the plant was Silene Maritima Otheriwse known as Sea Camion, or
CATCH FLY.

P.S. Thank you for the previous replies.
