This pretty pink and purple perennial is Malva Zebrina, commonly known as Hollyhock Mallow. My daughter saw it at the garden center and loved the pretty flowers, so we added it to my cottage garden.
I planted it in front of my tall hollyhock because the colors seemed to compliment each other nicely. I have no experience at all with this plant so I'm hoping it will survive the winter for many more years in my garden.
I've learned several things about hollyhocks:
1) The height is astounding! I knew these were tall plants, but still a little surprised by just how tall this one grew.
2) Snails love to eat hollyhock leaves
3) Japanese Beetles love to eat hollyhock blossoms
This particular hollyhock is a variety called "Creme De Cassis"
