As you may guess, purple is my favorite color. I planted the columbine from seed about 10 years ago. They pop up every year. Since they produce about a zillion tiny seeds per flower, I do not think they will be disappearing any time soon. I also noticed that the deer do not find columbine very palatable. That's a good thing. I don't have much of a garden anymore because of the deer thinking my garden is an all evening deer buffet.
This is Russian Comfry. It's a tough plant that the deer don't like, either. It also blooms most of the summer. It was in the garden when I bought the house. I just like it, so it has stayed. It also transplants very well. I transplanted a bunch of it in the front of the house about 2 years ago and it is growing like a champ.
