Aquilegia is regarded as dangerous, in particular the seeds and roots. However, their acrid flavor generally helps to avoids poisonings.
The flowers of various species of Aquilegia were noted as historically being consumed with other fresh greens, and are reported to be very sweet, and safe if consumed in small quantities. The plant's seeds and roots are highly poisonous however, and contain cardiogenic toxins which cause both severe gastroenteritis and heart palpitations if consumed as food. However, this plant is better avoided due to its high toxicity; columbine poisonings may be fatal.
We tend to err on the side of caution in PlantFiles, and the danger notation in the details above is to warn gardeners, parents, and pet owners to look further for more information.

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.
Flowers May-August
Likes a moist, well drained, humus rich soil in partial shade or sun.
