When I first started looking at wildflowers here in Ohio, I remember getting some of them confused with each other. This is embarrassing, but it goes with the territory when you are learning to identify new things, since none of us was born an expert at anything. Apparently I’m not the only person to be confused this way. One of the nifty tools that WordPress provides for bloggers is information on what search terms led readers to particular posts. ‘Yellow wildflowers spring’ with the occasional ‘Ohio’ thrown in has led more than a few people to my truly humble site. Back when I first started this blog, I did it in part because I wanted to learn more about the natural world, not because I was some kind of authority. This whole experience is a ‘let’s learn as we go along’ type of thing, and fortunately I’m learning more as time passes. You pick up things that are of interest to you.
An Ohio roadside in the spring
So, here we are in the spring again, and I’ve noticed those now-familiar yellow blooms coming up along the roadsides this past couple of weeks. So I figured I’d take a look at 3 of the more common plants with yellow flowers that are easy to spot this season, and how to tell them apart from each other. There are other yellow plants of course- including the abundant Dandelion profiled a couple weeks back- but we’ll save the other less common ones for some future post when I’m running out of easy subjects 😉
I ask your pardon for my concentration on the identifying marks that these plants have- that’s the way my mind works, and besides, the photos will show how handsome these plants are!
Apart from the abundant Dandelion, probably the first yellow spring flower along the roads one notices here in Ohio is Winter Cress, also known as Yellow Rocket. This plant is a member of the Mustard family, which means that like all Mustard species, it has a distinctive 4 petals on each flower. It likes growing in disturbed areas and along paths.
Winter Cress often has uniquely shaped leaves that clasp the stem. But the easiest way to identify this plant is by its clusters of light yellow flowers with 4 petals, each on a mini-stalk at the end of a main stalk.
The overall appearance of Winter Cress is bushy, with many blooms. Since it tends to be the earliest of the taller yellow plants, it’s a sign to me that spring is truly here, and its pleasant color heralds many other wildflowers to come.
This plant loves drainage ditches
There’s another yellow spring plant that particularly enjoys wet areas. This is Butterweed, a member of the Aster family, which means its daisy-like flowers will have many petals.
Butterweed has a thick stem terminating in a cluster of flowers. Its leaves are large and coarsely lobed. The stem reminds me of Wild Parsnip’s squat, coarse appearance.
A close look at the flowers definitely reminds one of Asters, though Asters typically bloom in the late summer and through the autumn, and they aren’t bright yellow . This plant is usually found in damp areas, and fields or ditches with standing water often are prime habitats. Its blooming season is often brief but prolific. The wetter the better!
There’s another yellow spring wildflower that’s a member of the Aster family- Golden Ragwort. This plant can easily be confused with Butterweed, since its flowers look almost identical.
Golden Ragwort will often be found along wood edges and in meadows. One way to distinguish it from Butterweed is its thinner stem.
Another identifying mark is the smaller sparse leaves. It will have larger leaves at the base of the plant, though these may be hidden in grass. The whole plant has a delicate appearance. There are other Ragworts that differ in minor ways with each other, but this one is quite common.
All three of these spring wildflowers attract insects, who are undoubtedly happy to see them in the spring. Winter Cress is eaten by animals, but both Butterweed and Golden Ragwort are somewhat toxic and avoided by many creatures.
There’s something about the warmth of yellow blooms, especially when they appear in the spring. They are happy signs that the drab winter scenery has been banished for many months. These three plants will be easy to spot this month if you’re out for a stroll or a drive in Ohio.
