Summer Sky

(Ageratum houstonianum)
Summer Sky Ageratum is one of the few truly blue annual flowers available and it absolutely shines in the summer garden! The incredibly rich blue flower clusters are made up of tiny pom poms with feathery petals. Plants form densely flowering, very long blooming, compact bushes about 1½-2 feet tall, providing rich garden color right up until frost. A wide range of pollinators and especially butterflies love visiting these flowers, and serendipitously both deer and rabbits avoid them!
