It is the end of August 2012 and the plant has just bloomed. It is located in a very shaded area in not so great soil which is dry most of the time. While the plant hasn't grown much it looks healthy. I'm in Raleigh, NC.

Love, love, love this plant! It has a beautiful blue color and goes with so many flowers. I have it with Carefree Beauty Rose, Apricot Daylily, and Spanish Eyes Black Eye Susan vine meandering around it: Beautiful! This plant is a "no care" plant. I originally had it in part shade and it was not very happy - moved it to full sun and it's done very well.
It will slowly spread through seed, but is easy to pull out the little ones you don't want. If you let the plants get big, then you almost have to use a shovel to get them out. The roots look kind of like white, crooked carrots.
It has nice yellow fall foliage so you get two seasons of interest. I cut mine down to about a 12 inches after the first round of blooms around June then, they re-bloom in August.

Exquisite blue, does very well in my zone 4/5 garden, very erect strong stems fan out making a nice structural accent even when not in bloom. It has not required any special care. I have not had good luck with divisions or transplanting, but beautiful addition to the perrenial bed just the same.

I absolutely love balloon flowers, and this dwarf version was my first ever. I also found these at Home Depot - I purchased three plants six years ago, I have since divided and shared with family and friends. They have never failed to return each spring, and I live in a very cold climate - regardless of what the zip code says. I can't recommend this flower highly enough - they bloom, and bloom, and bloom!

My favorite color of blue on sale at HD, so now we have them as a border. I wish they lasted longer in the season, but mine are all only 1 year old. We'll see how it goes. Showy and impressive in bloom!
