Photos of the Week – May 8, 2025

This week, I’ve found two different brief opportunities to poke around some local prairies with my camera. Both prairies were nice remnant (unplowed) grasslands with a good diversity of early season wildflowers, native sedges, and other little treasures.

My first stop was at Gjerloff Prairie, a terrific loess hills prairie owned and managed by Prairie Plains Resource Institute. It’s only about 20 minutes north of my house here in Aurora, so it’s a site I know pretty well. I usually try to visit at least once or twice each spring because it has some wildflower species I don’t see often in other prairies near home.

Big portions of Gjerloff Prairie were burned this spring, and recently enough that there weren’t yet any flowers blooming in those burned areas. That meant I had to walk further than usual to get to some unburned areas and open flowers.
Prairie ragwort (Packera plattensis) is a terrific little biennial.

False Solomon’s seal (Maianthemum stellatum) is a confusing plant to me (I still love it) because I first learned it as a woodland plant but it does well in the middle of some open prairies as well.

Later in the week, I took a break from other projects and wandered around one of our sedge meadow/prairie sites (Caveny Tract) at The Nature Conservancy’s Platte River Prairies. It’s a site with sandy alluvial (river deposited) soils, but still has a fair amount of overlap with Gjerloff Prairie in terms of plant species blooming right now. Prairie ragwort, pussytoes, and fringed puccoon are just a few examples. (For some reason a lot of the current wildflowers are yellow.) However, there are lots of different plants as well.

Yellow stargrass (Hypoxis hirsuta) is a “locally common” wildflower along the Platte River. It’s not in all sites, but can be very abundant in some.

The Caveny Tract includes more than 350 acres of prairie that is adjacent to hundreds of acres more. There are lots of little sedge meadow habitats embedded in the prairie, mostly in old swales formed by the meandering Platte River hundreds or thousands of years ago. Those swales are now close enough to groundwater to host a mixture of wetland and mesic prairie plants. Those sedge meadows, not surprisingly, contain both an abundance and diversity of sedges. In many places, you can stand still and see half a dozen sedge species within a few yards of your feet.

That’s assuming you’ve spent enough time with a dichotomous plant key to learn to identify some of the different sedge species. If you’ve never used a dichotomous key to identify plants, you’re missing a terrific opportunity to be overwhelmed by botanical terminology. I know enough to recognize differences between most sedge species and can identify the more common ones on sight. Every once in a while, I’ll grab a sample of one and run it through the key to stay in practice (and try to confirm my identification guess). It can take a while, mostly because I have to keep referring to the glossary to remember what a lot of the words mean.

If I did it more often, of course, I’d be better at keying plants. On the other hand, there are other things I’d rather be good at, so it’s all a matter of perspective and prioritization. I’m an ecologist, not a botanist, entomologist, or ornithologist. I don’t have to know all the species within any particular taxonomic group. I just need to know enough of them that I can recognize interactions between them. Or, at least, this is what I tell myself when I don’t feel like keying out plants.

I’m pretty sure this is Carex tetanica, one of many sedge species in the wet meadows of the Caveny tract and surrounding areas.

Here’s an example of what I mean about the terminology needed to quickly run through a plant key. The sedge pictured above is probably Carex tetanica. I think that because its lower pistillate spikelets appear to be loosely flowered, as compared to those on Carex meadii. Both species have perigynia with 2 strong marginal ribs and are glaucous at maturity. Their pistillate scales are also usually purplish brown on each side of the midrib.

If you’re a botanist, all the words in that paragraph probably make perfect sense (though you may also tell me that the pictured plant is Carex meadii rather than C. tetanica and I won’t argue with you). If you’re an ecologist like me, you’re content to live with a little uncertainty and keep some brain space reserved for other words and ideas.

These buttercups were thriving in a particularly low/wet part of a slough where a tree clearing/thinning project recently took place along the south edge of the Caveny tract. What species of buttercups are they? I have no idea. They’re really pretty, though.

The photographic highlight of my Caveny Tract exploration was a big patch of pussytoes (Antennaria neglecta) going to seed. I spotted the pale patch of fuzzy plants from 50 yards away or so. Growing right in the middle of it was a lone prairie ragwort plant. I found the combination of the two species really attractive and spent a lot of time photographing the ragwort flowers surrounded by the pale fluff.

These are just a few of the many photos I liked from the myriad composition options I played with. I used three different lenses to photograph the flowers, including a wide angle, a macro telephoto (180mm) and a longer telephoto (400mm). After I’d been shooting for a while, a little sweat bee arrived on the scene and kept me captivated for a few more minutes.

Later in the season, both of these prairies will have much bigger, more abundant, and showier flowers. Right now, the short stature and scattered nature makes most of the blooms are hard to see from the road. From that perspective, it doesn’t look like much is happening in the grasslands. Once you start walking, though, wildflowers are dotted around throughout and each one is a joy to come across. That’s especially true if you’re just appreciating their beauty and not worrying about whether their achenes are tuberculate or not.

Celebrating Seeds

I’ve been seeing a lot of brand new plants germinating from seeds during the last couple weeks. Looking at all those cotyledons (first leaves) poking out of the ground makes me reflect on the massive amount of good fortune it takes for any seed to actually turn into a new prairie plant.

Prairie dandelion seeds (Nothocalais cuspidata).

Seed production is a high risk, high reward strategy for plants, and even that’s a huge understatement. It takes a tremendous amount of energy for a plant to produce a flower – especially if you’re trying to make one that’s attractive to an animal pollinator. There’s all the colorful petals or other structures, nectar (in many cases), and, of course the pollen itself. After pollination, even more energy can go into loading up the developing seeds with the nutrition and energy needed to give the embedded embryo a chance of success.

Once the seeds are released from the plant, they often travel away from their parent – at least far enough that they aren’t trying to grow directly beneath them. The varied tactics used by plants to disperse their seeds is a huge, fascinating topic, which I’ve written about before. Regardless of whether a seed travels by wind, water, attached to the fur or feathers of an animal, or by being eaten and then pooped out, there are myriad dangers along the way.

Prairie violet (Viola pedatifida) seeds can travel in two ways. First, they are ballistically launched into the air as their pods dry and constrict. Second, many are picked up and carried home by ants because of the little fatty packet of nutrition (elaiosomes) violet seeds have attached to themselves for that very purpose.

Seeds packed with nutrients to feed their embryo are also a great food source for many other organisms. Countless vertebrate and invertebrate animals seek out and eat seeds, especially during the dormant season when most other food sources are scarce. Fungi and lots of microorganisms can also destroy and consume seeds.

If, by some minor miracle, a seed survives its short or long journey intact, it may still be a long way from ultimate success. For most plants, germination only happens if a seed is in good contact with soil. Think for a moment about the world a seed is launched into and how many obstacles there are between that seed and the soil!

When you walk through most prairies, if you look straight down, you’re not seeing a lot of bare soil. Instead, there are a lot of living and dead plant parts (leave, stems, etc.) between your feet and the ground. A recently-burned prairie, of course, has lots of bare ground. That’s a great opportunity, but only for any seeds who weren’t consumed by the fire itself.

Most seeds land on something besides soil. Often, that’s the end of their journey and they sit there until they die (e.g., the embryo runs out of stored food) or they’re found and consumed by another organism. If they’re lucky, they might get dislodged from their original landing spot by wind or rain, for example, and slip downward toward the soil.

Let’s say a seed has led a lucky life and manages to reach soil. It might even get pushed into that soil slightly by rain or a passing animal’s foot. Hooray! Now it can grow and reward its parent’s huge investment.

Well, maybe.

Most seeds need water to germinate. During drought periods, a seed might sit in the dusty earth for weeks, months, or years, waiting for sufficient moisture to help break its seed coat open. As it sits there, it’s vulnerable to any passing animal, fungal hyphae, or tiny microorganism looking for a meal. Plus, as we discussed earlier, the embryo might simply run out of food.

Even if rain or snow provides sufficient moisture for germination, some prairie seeds also need a certain amount of sunlight to trigger germination. (This is why it’s important not to plant prairie seeds like you plant pumpkin or green bean seeds. Just scattering them on top of the ground is often best.) If a seed that requires light lands on bare soil that happens to be in the shade of other plants, it might still be stuck in limbo.

Illinois bundleflower seeds have such a strong seed coat they can survive a trip through the digestive system of an animal. That’s great for the seed, but doesn’t provide any reward for the poor hungry animal!

As a result of all the challenges they face, only a tiny percentage of seeds released into the world by their parents actually end up germinating. Those that do have a chance to perpetuate the family line. However, simply reaching the germination stage isn’t the end of the race.

A tiny seedling still has to compete with any nearby plants for food, water, and sunlight. Only a small minority of prairie plant seedlings make it to maturity and create their own flowers and seeds. They either wither and die in the face of more competitive neighbors or get eaten by herbivores looking for fresh new growth to nibble on.

Despite the odds, of course, some seeds do manage to germinate and then become parents themselves. We’ve got abundant evidence of those successes all around us. It’s easy, though, to take those winners for granted. Spare a thought for all those who didn’t make it!I’m cheering on all the little germinating plants in the prairie right now. They’ve already survived a ton of obstacles, but they still have a lot to overcome.

I often wish seeds good luck when I see them, too (usually silently, especially if other people are around). While most seeds fail to become plants, each one of them plays a vital role in the prairie ecosystem. Animals and other organisms have to eat, after all, and seeds help keep lots of other community members alive.

Apart from everything else, seeds and the structures that help carry them into the world are simply beautiful. I’m incredibly appreciative of the diversity and aesthetic elegance of prairie seeds and I’ve spent a lot of joyful hours photographing them. I just try not to dwell too much on their individual survival chances…
