Western Columbine
Aquilegia formosa
Western Columbine typically grows 1 to 3 feet tall and features delicate, blue-green foliage that forms a compact, mound-like base. From late spring to early summer, it produces eye-catching, nodding flowers with red sepals and yellow petals. The unique flower shape and bright colors are highly attractive to hummingbirds, which are its primary pollinators, as well as various butterfly species.
Western Columbine thrives in partial to full shade, preferring moist, well-drained soils rich in organic matter. It is an excellent choice for naturalized areas, shady borders, and woodland settings where its natural beauty can complement other shade-loving plants.

Maintenance Tips
- Keep soil consistently moist but not waterlogged; water regularly, especially during dry periods.
- Deadhead flowers to encourage additional blooming and to prevent excessive self-seeding.
- Prefers rich, loamy soils but is fairly adaptable. Enhance poor soils with organic compost to improve nutrient content and moisture retention.
- Apply a layer of organic mulch around the base to retain moisture, suppress weeds, and keep root systems cool.
- Monitor for leaf miners and aphids, common pests for columbines. Treat with environmentally friendly options if necessary.
