Colorado Blue Columbine (Aquilegia coerulea)
A Botanical Illustration Guide
Colorado's state flower is one of the most distinctive plants in the Rocky Mountain region — and one of the most rewarding to draw. The columbine's combination of spurred petals, delicate sepals, and a dense central cluster of stamens makes it structurally unlike almost anything else you'll encounter in botanical illustration practice.
This is a guide to approaching Aquilegia coerulea as a subject: its key identification features, the structural challenges it poses, and strategies for drawing it accurately.
Identification and Natural History
Aquilegia coerulea grows wild across the Rocky Mountain region at elevations from 6,000 to above treeline. The flowers are typically blue-violet with white inner petals, though color varies from pure white to deep purple. It blooms from June through August depending on elevation.
The name Aquilegia is thought to derive from the Latin aquila (eagle) — a reference to the curved nectar spurs, which resemble a bird's talons. The spurs are the key diagnostic feature that distinguishes columbines from all other flowers.
Key Structural Features to Understand Before Drawing
Before putting pencil to paper, it helps to understand what you're actually looking at:
- Five spurs: The backward-pointing tubes on the outer petals are hollow nectar spurs. Each has a small knob at the end. They're botanically part of the petal, not the sepal.
- Five sepals: Spreading, petal-like, and similar in color to the true petals. Many people initially draw columbines as if they have ten petals — but five of them are sepals, and they're arranged alternately with the spurred petals.
- The stamen cluster: The dense central column of stamens is what gives the columbine its characteristic warm yellow-white center. There are many individual stamens, and they're worth studying carefully — they're not just a blob of yellow.
- Compound leaves: Columbine leaves are ternately compound (divided in threes, then divided again). This biternate structure gives them a very distinctive look and is a key identification feature.
Approach to Drawing the Flower
The most common mistake when drawing columbines is flattening the flower into a single plane. In reality, the spurs project backward while the sepals spread outward and the petals cup slightly inward. It reads very differently in three dimensions than in a pressed specimen.
Start with the geometry: the flower has five-fold radial symmetry when seen from the front. Establish that axis first. Then work outward to place the sepals, which are the most visible elements in a front view.
The spurs are easiest to understand and draw from a side or three-quarter view. A pure front view will foreshorten them into small ovals at the back of the flower. If you're drawing from life or reference, try to find an angle that shows at least two or three spurs clearly.
Drawing the Leaves
The biternate leaves are both a challenge and an opportunity. If you're doing a full botanical study, they're essential — columbine leaves are diagnostic. But they're also extremely complex if you try to draw every leaflet individually.
The key is to understand the structure before you draw it: each leaf divides into three groups, each of which divides again into three leaflets. Once you see that pattern, you can draw it systematically rather than trying to copy a tangle of overlapping shapes.
Practice with the Tool
The Botanical Gesture Lab regularly pulls columbine specimens from iNaturalist when you search for Colorado flora. The timed gesture sessions are a good way to build up your visual vocabulary for columbine structure before attempting a detailed study — especially useful for internalizing the angle of the spurs and the spread of the sepals across different specimens and views.
For detailed work, iNaturalist has thousands of high-quality Aquilegia coerulea observations with precise location data, many of them from Denver and Rocky Mountain National Park.
