I copied the list and didn't go through it. Delosa is a natural hybrid, maybe that is why they included it.

Stretching my personal likes & dislikes, C. guttata/leopoldii/tigrina would be my choice. Flower colors vary greatly & they have a wonderful head of flowers on a mature plant. They do grow tall which is a possible downside.

BTW, C. Dolosa is a natural hybrid, not a species.
