REINDEER ANTLERS is a fantastic plant in my Zone 5 garden. Once established, it reached its registered height. Blooms for a long period of time. It is usually a ML bloomer. It increases at a moderate rate. At times, it almost has a blue red color to it. My only complaint is that I find it difficult to get an accurate picture of it. Nan's third picture and Avedon's 3rd and 4th pictures are pretty close to what I see in my garden. It is a worthy addition to the garden.
