Just to add my 2 cents. I never met a plant I did not like. If I did not plant something because everybody had one I would not have one tree in my yard. Everybody in my neighborhood have trees.
When I plant my gardens it is for look and smell. If I want fragrance I add fragrant plants, if I need a certain color flower and if the knock out fits that color in my garden in it is going. I guess it is like 2 women wearing the same dress it can be a killer on one a beauty on another. It depends on what someone puts in that dress.
There are a bunch of roses out there without smell. Believe me I have had a few. You could not smell them unless you stuck your nose in it and sucked up the darn bee in your nose. But it was a pretty color so I liked the rose. It just does not matter to me I call it a flower, and as long as it flowers I do not care what they call the plant. JMO
