This ‘old school’ summer blooming beauty still captivates each summer with its collection of double, purple-blue, 3″ diameter flowers that bloom from early August into September. This was always a favorite for Moms and Grandmas alike and its easy to see why because it never fails to produce a massive color show on a plant that will dominate the summer landscape in a good way. Easy to grow and wanting little care once established, this sun lover can make the perfect single summer specimen plant or can be very functional grouped together to form a taller, broader border planting will only magnify it blooming power in the landscape.
