My 'experimental experience just for a 'wild small garden' just started this year when i boughted Aquilegia 'Crimson-Red star' to join some other 2 aquilegia, vulgaris and caerulea i already had; when 'Crimson star' bloomed, this week, i got the expected 'red & white center' flower; BUT from the same plant i had also a 'white flower', which i suspect comes from a 'mutation' ou from the hybridization process of the 'crimsom star'. An amazing flower and plant.
Maybe next time i come here i do an upload for all of you.
NOTE: i'm just an engineer (not a gardener) that like botanics!!

I've had this since '05 and I think it is my prettiest columbine. I love the red and white flowers and this year my plant had dozens.

A pleasant columbine that provides masses of cheery flowers. It doesn't seem to be susceptible to many maladies that some other columbine are.

Having grown several strains of Columbines, this is one of my favorites. However, this particular cultivar is sensitive to severe cold and prolonged freezes (5a/b). At best I am only able to grow it for a maximum of three years, and then only if winters are not severe, and there is a thick snow cover. Even under these conditions it is a worthwhile plant. Other cultivars such as the 'Nora Barlow' and 'siberica' thrive and flourish here without regard to cold.

The Columbine Crimson Star produces red flowers with a yellow center. Aquilegia grows best in partial sun to partial shade.
