I was not sure if they make through the winter but everything went well and nearly all plants started to grow in the spring.
The flowers are a bit bigger than in any of the other columbines I have. The package I bought was a mix of different colors but this far only one of the colors has bloomed.
In other words I still am waiting for the others to start their show and reveal their true colors.
PS. Bought the seeds from a local store. McKana variety is usually widely available.
