Hybridized in Minnesota by Karol Emmerich and introduced in 2009, this dormant tetraploid grows 28 inches tall with 5 inch blooms. I have my plant growing at the front of a border because the unique blooms are so showy and attractive. Profound Mystery is a no-fuss, hardy grower in Wisconsin. Last summer, in my garden, it bloomed from July 7 through August 13.
