Wow! I find it impossible to say enough in support of this absolutely beautiful perennial and have found it to be very hardy here in the upper region of the Sunbelt.
Our first spring in Tulsa, Oklahoma was in 1977 and among the very first perennials that I experimented with were none other than several Columbine or Aquilegia varieties.
If I remember correctly the two varieties that I grew from seed were Crimson Star and McKana Hybrids which prospered well in shade and semi-shaded areas and even managed to exist in full sun.
When planted in full sun I found that each varieties anticipated height was vastly reduced but otherwise grew and flowered in an acceptable manner.
However, I do suggest that the best exposure in the garden would be under shade and semi-shade conditions as this is where they really thrive.
A gardener will be able to select from forms that will only reach up to five inches in height to as much as three feet. Many of the available colors are two tone or bicolor along with solid shades as well.
Colors range from deep blue through the following list:
pink
purple
light blue
white
red and yellow bicolor
yellow
red and white bicolor
rose
crimson
violet-blue
and others with one featuring fully double flowers in a combination of red, pink and green.
Use these in the alpine or rock garden or in the landscape bed as you so desire as you will not be disappointed.
