One of my favorite columbines. It winter-sowed beautifully, and the plants are incredibly vigorous. I love the blue-green foliage, which is semi-evergreen in this climate, and the spectacular long-spurred yellow flowers.

This is the first time I've seen yellow columbines growing in my town. I've only had purples/pinks. It is growing well and I hope it will spread to beable to share it with my friends and family who love it too!
Has soft, mid green leaves divided 3, leaflets are lobed and gives the plant a ferny appearance. Bears outward to upward facing, pale to golden yellow flowers, some may have a pinkish tinge especially when the flowers age.
Likes a moist, well drained, humus rich soil in partial shade or sun.
