    I live this plant so far! I planted three small quart-sized pots of this cultivar this spring and right now I have 4.5 feet tall stems with large, ever expanding candelabras of a gorgeous irridescent blue-violet shade. The flowers swarm with a wide array of wonderful pollinating insects. One of my favorites in my new perennial garden!

    My favourite culver's root.
    The flower spike in front of the tree trunk (on the right) in my photo shows fasciation, which this cultivar is noted for.
