    Justly renowned iris.
  • Posted by Marilyn (Kentucky - Zone 6a) on Dec 1, 2011 12:42 AM concerning plant:
    This is a gorgeous flower! I only had it in bloom for the first time in 2010 after planting it the Fall of 2008. The color and height are stunning! I'm not surprised it won the Dykes Medal! Everything about this plant is wonderful! If I had to grow one Tall Bearded Iris, this would be the one! It's truly a winner in all aspects! It's been in the Top 10 of the Iris Society Poll for years and for good reason!

    I got rid of all my Irises in the Fall of 2010, but I've been tempted to grow this one again! It's so beautiful! I just might have to make a spot to grow 'Dusky Challenger' again!
