I had let this plant go this year,without pinching it back & it is now over 5 ft tall with thousands of blooms! Next year I will pinch it back, but in the meantime the branches form a neat tall cascade, attracting lots of butterflies! We are officially zone 5 in Missouri, but many of my plants thrive as though it is zone 6.
