Love this plant - it's been in bloom in my garden for weeks, deep blue/purple blooms against cotinus Velvet Cloak, with Hot Lips turtlehead & Becky shasta daisy. Little Lamb hydrangea, sedum Autumn Joy, and a big clump of soft gold mums nearby. It looks wonderful with all the golds of the turning leaves and dusty pinks of the fading flowers. Very tall beside the rock wall around my patio. Full sun, soil on the dry side. Four plants so far, and I want more - I'll try scattering seed once it ripens. What's better than a fall garden in bloom?

This provides an interesting specimen all growing season. It has deeply serrated leaves and tall spires that do not go unnoticed. In the early fall when little else is left to bloom these put on a display of beautiful purpley blue blossoms. They grow heartily in my New England cottage garden.
