I love this plant! First saw a picture of in the newspaper some years ago when it was an All America selection. Sadly, they didn't come back this year and I had to order new ones from High Country Gardens, who are the exclusive sellers. It was growing in medium shade-I will move it to a sunny spot this time.

Swallowtail is by far my favorite Aquilegia to date. Not only does it produce uniquely beautiful flowers in abundance it produced flowers into early summer. Equally as important it has proven to be a very strong healthy plant not succumbing to insects, a forgotten watering or dead growth. I purchased this cultivar as well as Chrysantha, Red Hobbit, Little Treasure, and desertorum from High Country Gardens, all have produced well but none as spectacularly as Swallowtail.

This is the first year that I have had this plant. I planted it last Fall. The plant now has many, many blooms and more coming.

This is a real honey of a plant. It tolerates all-day hot sunshine. Its foliage stays green all summer. Its flowers are large and bright yellow. Much of the foliage stays green all winter as well. It tolerates temperatures in the 20s (F). It comes true from seed.

This plant has its origin in an Arizona species and is heat-tolerant - for a columbine.
