they sell an a lot of those roll out
flower things, and do so year after year. So I guess they must work, at least to some extent. But it is like Tamara says, it depends on what kind of look you are going for.
My daughter had a wild
flower bed she grew from a package mix last year, and I must say it was beautiful. She did pass comment on how there was a very pretty
flower "down in the middle" of the bed, and could no longer be seen due to the height of the outlying
flowers.....
