I planted this last year in hard soil which was under a cement pad which I removed. It was planted through landscape cloth. The blooms were pink. This year the plant tripled in size and is covered in bright red blooms. I love it!
Attracts some butterflies in my experience but not well enough for me to justify its spreading from reseed many feet away from the original plant. I dug it up and am in the process of trying to eradicate the sprouts.

I was given this plant at a garden club trade and it was labeled "red yarrow." It seemed puny and took a bit to take off, but wow, it is a nice little performer in my garden. This will be my third year having it and I have enough of a clump to divide it several places, so it is a good spreader, but not invasive (so far) for me. The plant is fernlike in spring and is a very pleasing foilage, soft and dark green at first. By late May or early June it begins to flower and does so until frost in my Indiana garden. Looks very good with deep purple and blue flowers in a mixed bed. I use mine as a filler with Bachelor buttons and feverfew around a Nikko Blue Hydrangea and the effect is striking. I have seed for white yarrow this year. I also posted a picture. Happy Gardening!

I just love this showy color. It starts out as a crisp, true red, then fades to a softer pastel red while the yellow "eyes" pop out more. Doesn't spread as quickly as other yarrow varieties I have so it's easy to control.
