Absolutely arresting rich cobalt-blue blossoms paired with near black stems. These tall flower spikes are produced from midsummer to mid-fall, earlier in warmer climates. Deadheading will prolong the bloom time. Hummingbirds, butterflies, and bees devour their delicious nectar. Hummingbirds love this one!
