Saucy Seduction is doing great this year. I divided it and moved it in front of thePolar Star daisys this Spring because last year the daisy was much taller than SS. This year it looks like they are about the same height or the yarrow may even be taller..
Here's the same two last year. Notice how much shorter the yarrow was.
Makes me wonder if next year the daisy will be taller again.
