Delicate, perfumed phlox;
A mist of columbine, clinging to earth;
Phoebe’s gravelly voice,
Titmouse — tender, sweet;
A dogwood cloud hover above
Vibrant, fresh leaves.
Falling flowers, already spent;
A garden, no longer my own.
A spring, a garden, will come again;
At home in the hope, the beauty.
Mike has shared some of my poetry on his blog in the past; the poem above is another of mine. In fact, it’s the first I wrote as an adult. I went to a poetry session at an Outdoor Classroom Symposium at the NC Botanical Garden that was taught by a couple of teachers from South Carolina. The teachers gave us a few templates to get started, and sent us out along the garden paths to write. I found a spot amid a patch of beautiful columbine flowers. The first activity was simple – use your senses to observe the world around you, and pay attention to how that makes you feel. The poem above is the result of that short, sweet writing exercise. I have used the same simple steps many times since then in my own writing, and I’ve shared that activity with numerous teachers through my work. I’m incredibly grateful to those two teachers for reintroducing me to the world of poetry-writing!
But now, it’s time for our next flower parts adventure… this time we’ll take a close look at wild columbine (Aquilegia canadensis). Wild columbine is one of my favorite spring wildflowers, and we have an abundance of it in our yard. The flowers hang on delicate stems and look like they’re floating above the ground. Each plant produces numerous blossoms over the course of at least a month in our yard. In fact, a couple of years ago, one of the earliest blooms managed to get caught in a late winter snowstorm…
Because its so ubiquitous, it was an early target for my plant parts explorations – I didn’t feel too terrible taking a few blossoms off the plants when they were so numerous! Like the wood poppy, it is a simple flower, but because of the odd shape of some of its parts, it’s a little more challenging. As with the wood poppy and dogwood flowers, my first task was to find the sepals.
Given the overlapping nature of the flower’s structure, this was tricky. Which are the sepals, which are the petals? I took off one of each to see if I could tell…
It was still difficult to tell which was which, even after removing one of each part, though it seemed as though the smaller, leaf-shaped parts were attached higher up on the stem than the long, spurred ones, which would make them the sepals. I looked for some flower buds for confirmation, and indeed, the leaf-shaped part enclosed the bud before it opened. Mystery solved!
In these two images, you can see how the petals’ spurs extend and start turning red very early in the flower’s development. In the image on the right, you can even notice the developing stamens inside the flower bud; and in the right-hand image, the elongated stalks extending out of the flower bud are the undeveloped pistils (more on that in a moment). The spurred petals have a nectar reward in the bulb at the top where long-tongued pollinators like butterflies and hummingbirds can access it (while conveniently rubbing their bodies or heads on the stamens or pistils).
Since columbine blooms for so long in our yard, it was easy to trace the development of different parts of the flower by finding a sequence of ripening flowers.
In an early bloom, the stamens, with club-like yellow anthers on the end, slowly uncurl, with the interior stamens dropping first. Notice how, at this point, the stamens and pistils are about the same length. As the flower continues to develop, that changes.
The flower in the next two pictures is further along than the last one, and you can see how nearly all the stamens have fully uncurled. The pistils have also lengthened, and their tips have opened up as they’ve become receptive to pollen.
An interesting pattern among many flowers is that their parts often occur in multiples. The columbine is a great example of that. It has 5 sepals, 5 petals, and 5 pistils. And when I took the time to count the stamens on one flower, there were 40 of them (which is a multiple of 5!). Another example of this is with Easter lilies, a flower you might be familiar with, and perhaps appropriate to mention as we approach Easter weekend. Easter lilies (as well as other lilies) have 3 sepals, 3 petals, 6 stamen, and 1 three-pronged pistil. Maybe this is a new tool for teaching the multiplication tables for those of you who are now homeschooling your kids?
When the columbine flower is finished blooming, the sepals, petals, and stamens fall off, leaving only the 5 pistils behind. They slowly turn upright and the ovaries at the base begin to swell. Eventually, they will open up like 5-sectioned cups, full of dark-colored seeds that bounce out when you brush up against the plants. But for now, the seeds are still developing.
As with the wood poppy, I gently opened one of the one of the ovaries to see the seeds developing inside.
As with the other species, I was again fascinated by the way the columbine has adapted its structures to an entirely different arrangement. Flowers are so cool!
