Don't say goodbye to summer too soon. These days summer can stretch into early October, and the traditional midsummer floral display seems like a flash in the pan. Where once gardeners threw all the big guns at June and July, you now need a second set of late-flowering plants to see you through September and October.
Few of us plan and plant for autumn bloom. But September and October don't have to be only two months of falling leaves and waning blooms in the garden. There are several perennials that work hard to bloom in the garden right through September.
