McKanna Giant is the standard for large flowered tall Columbine. Hardy to zone 3, they seem to be happier in locations with cooler summers, but may behave as a fall planted biennial would in hot climates.
Kirigami is a fast grower with reduced vernalization requirements, making it a good choice for warmer climate growers and cold climate growers alike.
