I often find the terms are very loosely used and confusing.
What do you guys think?
I always think of.........
Scent: something that you can only smell If you sniff a flower directly. eg, primroses.
Fragrance: is stronger than scent and can be smelled without sniffing a flower directly, say in passing close to a plant. eg, roses.
Perfume: Is the srongest and can be smelled from a good distance away. eg honeysuckle.
