    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.

    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!
