  • Posted by Chillybean (Iowa - Zone 5a) on Aug 11, 2015 10:21 AM concerning plant:
    This plant is a butterfly magnet! It would be glorious to see if the whole plant would bloom all at once, but it starts at the top and works its way down. This is ideal because it provides food for a longer period of time.

    This site says they get up to 36 inches tall, which matches the description offered by the company I get most of my plants from. In my case, some of the plants have gotten as tall as I, and I am a little under 5 and a half feet. Many of mine are in part shade and we have mesic soil in those areas. The plant likes to expand, so this may be a concern for those who have a small space.
