This is a unique flowering plant. Unique in that it flower’s blue, and that it looks like a little balloon before it pops open.
There are other flower colors available, white and pink; but blue seems to dominate because of its rarity in the plant world.
One other aspect that makes this perennial great in the landscaping is the fact that it blooms in the late summer; during a time of very few bloomers. It can look rather “green” out there during this time, the Balloon Flower breaks up this visual monotony.
They are rather fussy when it comes to too much or not enough water. So don’t feel like you’ve got to standing over them with a hose; but don’t assume they’re getting enough with the passing showers.
So if you’re looking for something different, reach down and find the “kid” in you and plant some balloons.
