I have always liked the native and have some of those, too. This is a cross between a native and one of my purple ones from years ago. The rest are those I started from seed as a mix. If you have never started columbine from seed, it can be a worthwhile project. They will self seed on their own, but like to mix it up, and there is no telling what you may get, a bit like Forrest Gump's box of chocolates.
Some are singles, doubles, ruffled, or "bonnets". Some are a single color or bi-colors. Some are shorter or taller, with bluer foliage. They can form nice clumps and weed out easily. They also come in yellow and white, but those tend to be the last in bloom.
