Rudbeckia and butterflies
I have gradually been converting the backyard to plantings of native perrennials and have noticed a gradual increase in the # of butterflies. However, I notice that they don't spend much time on the rudbeckias. They completely ignore R. Fulgida Goldsturm. I also have R. Triloba -- these get some visits but the butterflies only seem to stay on each flower a moment or two. I always heard that Rudbeckias were good for attracting butterflies. Are they overrated?
