The nutrient-poor conditions of bogs and fens present a challenging environment for plant growth, so some plants have evolved mechanisms to obtain extra nutrients in interesting ways. The three special plants found in these habitats in Michigan are pitcher plants, bladderworts, and sundews. Carnivorous plants have always been a favorite of mine because of their ability to live in extreme environments and thrive by eating insects! It is also really fun to watch slow motion videos of flies being captured by the infamous Venus flytrap!
Pitcher plant (Sarracenia purpurea) can be found in bogs or fens all over the great state of Michigan, including the bog at Cranberry Lake Park. The highly modified leaves are curved into a pitcher-like shape, thus giving the unique carnivorous plant its name!
Pitcher plants in particular attract insects with their brightly colored, highly modified “pitcher” leaves that mimic flowers. Insects crawl down into the leaf and get trapped! Downward pointing hairs and a waxy coating on the inside of leaf prevent the insect from escaping, and enzymes produced by bacteria in the liquid at the bottom on the leaf digest the insect. A “pitcher” perfect ending for the plant, but not so much for the insect!
Have you found a carnivorous plant while walking through a fen or bog in your area? If you have, comment below! We would love to see your photos and hear about your experiences with cool carnivorous plants!

It’s too easy to just visit an area once and think you know it. Visit your favorite woods, stream, or prairie once a week this summer and really pay attention to what you see. It is always changing.
I was reminded of this constant change while preparing for upcoming invasive shrub removal at the Paint Creek Heritage Area Wet Prairie. I couldn’t find the blue-eyed grass I’d noticed a week earlier, and the prairie grasses were growing quickly! What I really enjoyed, though, were the new flowers that had opened, spreading swaths of new color into the patchwork of the prairie.
The first yellow flowers of shrubby cinquefoil (Dasiphora fruticosa) had just emerged, foretelling a golden show in the coming week. You might recognize this attractive shrub because it is sometimes used in landscaping. Shrubby cinquefoil is fairly common just beyond the park sign along the Paint Creek Trail, so you won’t have to look very hard to find it.
Pale purple spikes dotted the prairie. This species was a new one for me – my best guess is pale spiked lobelia (Lobelia spicata), but let me know if think otherwise! The “3+2” pattern of the petals resembled the close relative cardinal flower (Lobelia cardinalis): notice the 3 bottom lobes of petals and the 2 top lobes. The delicate purple flowers seemed to be more abundant in slightly disturbed areas.
I’d noticed hairy beard-tongue a week or so earlier, but I can’t resist showing it to you. Like a lot of common names, hairy beard-tongue is a rough translation of the Latin name, Penstemon hirsutus. Scientists were very descriptive when they named these plants! Hairy beard-tongue likes sandy, open ground, including prairies and the oak barrens that used to be abundant in this area.
Lastly, butterfly weed (Asclepias tuberosa) is getting ready to pop! Next week we’ll have a glorious display of deep orange milkweed flowers all along the Paint Creek Trail north of Silverbell. Don’t miss it!
Let me know if you see these plants flowering at Paint Creek Heritage Area – Wet Prairie, or if you see something new!
