Iowa wildflower Wednesday: Poison hemlock
Radio Iowa reported on June 14 that Hancock County Weed Commissioner Jason Lackore “is sounding the alarm” after finding poison hemlock in two public areas upstream from sites where cattle producers let their animals graze.
“If it was any other plant, I wouldn’t be making such a fuss, but this plant — all parts are extremely poisonous to humans, domestic animals,” Lackore said. “And you hear a lot about livestock, cattle, ingesting small amounts. It’s fatal.”
Poison hemlock (Conium maculatum) is best known as an ancient method of execution, used to kill the Greek philosopher Socrates. This European native has unfortunately spread across the U.S. and is prevalent in Iowa. I see it almost every day while walking my dog. I took all of the photos enclosed below less than a mile from my home in Windsor Heights.
Habitats where poison hemlock thrives “include edges of degraded wetlands and prairies, low-lying areas along small rivers, banks of drainage ditches, thickets, woodland borders, fence rows, low-lying areas along railroads and roads, pastures, and abandoned fields.” You will mostly likely find it on disturbed ground, such as near railroad tracks or pavement. This patch is growing next to the parking lot behind the “Sherwood Forest” strip mall on Hickman Road.
That purple sign reads “prairie restoration.” It went up around twelve years ago, when a local student seeded a prairie patch in this area for his Eagle Scout project. Unfortunately, with no one maintaining the plantings, the field became overrun with invasive plants within a few years. I rarely see prairie species there anymore.
There’s no natural check on poison hemlock; according to Illinois Wildflowers, “Mammalian herbivores won’t touch the foliage because of its bitter rank odor and extreme toxicity.”
Like wild carrot, which it resembles, and other members of the parsley family, these plants are on a two-year cycle. Basal leaves grow during the first year, and the flowering stalk appears the following year.
The next image shows the plant in its first year.
In the second year, poison hemlock plants typically reach heights of three to eight feet. I’ve seen them much smaller, though; this one was barely one foot tall.
Some native plants—such as common elderberry and cow parsnip—also have clusters (umbels) of small white flowers blooming in May or June across Iowa. But the leaves and flower clusters on those plants look quite different.
Minnesota Wildflowers notes another distinguishing feature of poison hemlock: “The main stem is light green and covered in purple spots.” You can see a splotchy stem on the right side of this image.
After the blooming period, the foliage turns yellow, and the stems may look mostly red, rather than splotchy.
I struggle to photograph poison hemlock flowers, which “span only 1/8″ (3 mm.) across when they are fully open.” This plant has buds on the verge of opening as well as clusters of flowers in full bloom.
More flowers open:
Getting a clear view of the green fruit as it develops is also challenging. These plants have some clusters of flowers open and other clusters of green seed pods.
Eradicating poison hemlock is not easy. Illinois Wildflowers advises, “In removing this plant from a given area, don’t pull it out using your bare hands. It is better to wear washable gloves while hand-pulling a limited number of plants. For large areas of infestation, it is best to apply broadleaf herbicides or mow down the plants during the spring shortly before they develop flowers.”
Nadia Hassani wrote on The Spruce website,
Small first-year seedlings can be removed by hand. After a rain when the soil is moist is best to remove the entire tap root. You might have to use a trowel or a shovel if the rosette is already big.
If you are dealing with a heavy infestation and a large area, mowing the infestation repeatedly helps to weaken the plants. Mowing must be done in the early summer before the plant has set seeds, otherwise you are dispersing the seeds even more. Mowing in the late summer after poison hemlock has gone into see[d] also poses a greater health hazard.
If you cannot get the infestation under control manually, it is best to use a broad-spectrum herbicide in the first year of the plant’s life cycle.7 Keep in mind that it will also kill all the other plants so apply it in a highly targeted way and when there is no wind to avoid herbicide drift. Applying an herbicide does not prevent seeds that are already in the soil from germinating (poison hemlock seeds remain viable for up to six years)8 so you will likely have to repeat the herbicide application when new seedlings emerge.
I hate to advocate for herbicide in any context. But look what can happen if you don’t get poison hemlock under control. This colony is growing in a retention basin just steps away from the parking lot of Clive elementary school, my alma mater (which is now called Clive Learning Academy). I’m talking about the taller plants that are turning yellow.
Here’s the view from the other direction. I believe the poison hemlock surrounding that cluster of eastern cottonwood trees in the background likely provided the seed base for the plants now growing in the retention basin. I’ve seen poison hemlock around those trees since I learned to identify the plant a decade or so ago.
As I mentioned above, poison hemlock does well on disturbed ground, so this European invader would have easily found a foothold after the West Des Moines school district built a circle drive behind Clive school.
Moving closer to those trees, which are growing next to the bike trail that runs through Windsor Heights along North Walnut Creek, you can see the poison hemlock more clearly.

Iowa State football coach Jimmy Rogers assesses the Cyclones’ spring
Iowa State football coach Jimmy Rogers assesses the Cyclones’ spring
Spring commencement arrives at Iowa State this weekend, with a whole new generation of Cyclones set to get their diplomas and move on to the next things in their lives.
The options and choices will set their path for, potentially, the years and decades ahead.
Which got me thinking about the choices and circumstances of this school year that came for Iowa State athletics. There were no shortages of inflection points at which, it seems, programs and an entire athletics department pivoted to new directions.
Let’s explore.
What if Iowa State had hired Taylor Mouser as head football coach?
This seems to be the most discussed “Sliding Doors” moment for Iowa State football fans regarding head coach Matt Campbell’s departure to Penn State. And with good reason. It’s the most obvious, could have had the most immediate impact on the program and would have been largely seen as a continuation of the most successful run in school history.
Would promoting the Iowa State offensive coordinator, though, have been the right move?
If you assume a best-case scenario in which some of the star Cyclone players on offense – think Rocco Becht, Ben Brahmer, Carson Hansen, etc. – stay at Iowa State and a bulk of the coaching staff does as well, there are still likely defections that weaken the roster. Nothing like we saw back in December, but, still, there would be holes – and Campbell’s shoes – to fill by a first-time head coach taking over for a legend.
The calculation, as I see it, has to be – does the Year 1 continuity and relative stability gained by hiring Mouser provide for better long-term results than hiring Jimmy Rogers, who has the benefit of head-coaching experience?
It certainly would have made the fan base feel better back in December, but would it have positioned Iowa State to have better results in 2027 and beyond?
The roster almost certainly would have been “better” in 2026 if Iowa State retained Mouser, but would that have created a more solid foundation for the future or just delayed decay?
This “What If” becomes a lot less intricate and interesting if Rogers just wins a ton this fall and going forward.
What if Penn State had been able to hire Kalani Sitake as its football coach?
I think this is the most interesting question on the list.
By reports, Penn State was on the verge of hiring Sitake from BYU when the Cougars’ boosters – led by the Crumbl Cookie fortune – banded together to put together a financial package to keep Sitake in Provo.
What if they hadn’t, though?
Sitake goes to Penn State, and Dec. 5, 2025, is an uneventful day in Iowa State history rather than one of its most feverish.
But … what happens a few weeks later when Sherrone Moore is fired at Michigan?
Rather than plucking 66-year-old Kyle Whittingham from Utah/forced retirement, do the Wolverines try to make a Michigan Man out of an Ohioan? Does Campbell inherit the seat of Bo Schembechler?
And, for the sake of this thought exercise, if Campbell did move to Ann Arbor, does the timing of that decision change athletics director Jamie Pollard’s options and calculus about Iowa State’s opening? Is Jimmy Rogers still available? Or would he have taken a different opening or opted not to leave Pullman at that later date? Is Mouser the answer in this scenario?
Or is the Buckeye State distaste for the state Up North too much and Campbell returns for Year 11 at Iowa State?
Addy Brown on what went wrong in Iowa State’s loss to Syracuse
Iowa State’s Addy Brown talks about her team’s struggles in a loss to Syracuse in the NCAA Tournament.
What if Addy Brown doesn’t get hurt?
Iowa State women’s basketball was 14-0 on Jan. 4 when it played Baylor in Waco, and the season felt sure to realize the potential that was clear before it started with one of coach Bill Fennelly’s best rosters.
The Cyclones, though, returned home with their first loss and with Addy Brown sidelined with a back injury.
Four more losses in a row followed, and when Brown returned to the floor after six weeks, the Cyclones’ season was floundering.
They salvaged an NCAA Tournament bid, but a first-round exit gave way to a roster collapse with nine players – including Brown and superstar Audi Crooks – leaving via the transfer portal, putting Fennelly’s tenure and future under fire.
If Brown doesn’t get hurt – or just isn’t out as long – does that change the trajectory of the season? The offseason? And what the eventual end of Fennelly’s Iowa State career looks like?
What if Joshua Jefferson doesn’t roll his ankle?
The most recent “What If” I think is also the most straightforward.
If Jefferson’s ankle doesn’t roll in the early minutes of Iowa State’s first-round NCAA Tournament blowout win over Tennessee State, I think the Cyclones get a long second weekend in Chicago, but the Final Four drought probably remains intact.
Jefferson’s rebounding and offensive impact are, I think, enough to give the Cyclones the edge against Tennessee, but Michigan, the Cyclones’ would-be Elite Eight opponent, was just a juggernaut.
I’m not sure even a full-strength Iowa State team would have had more than a puncher’s chance. The Wolverines were just one of the best college basketball teams we’ve seen over the last few decades.

One of the top Iowa high school football prospects in the state has made his college decision official.
Iowa City Regina High School senior-to-be Tate Wallace has announced he has verbally committed to the University of Minnesota in the Big Ten Conference. Wallace picked the Golden Gophers and head coach PJ Fleck over a finalists Notre Dame, Nebraska, Arizona, Arizona State and Wisconsin.
Wallace narrowed down his list of schools to six at the end of April before making his final decision.
Iowa City Regina Football Standout Tate Wallace Ranked As No. 2 Overall Prospect In Iowa High School Football
The 6-foot-2, 226-pound linebacker is considered the No. 2 overall prospect in the state of Iowa for high school football, and is the No. 21 linebacker in the Class of 2027, according to 247Sports.
In the 247Sports Composite rankings, Wallace is No. 2 in Iowa high school football, No. 29 at linebacker and No. 359 for the Class of 2027.
Along With Minnesota, Tate Wallace Currently Holds Offers From Schools Such As Arizona, Nebraska, Wisconsin, Notre Dame, Tennessee, Iowa State
Wallace currently holds 16 total offers including from the previously mentioned Minnesota, Notre Dame, Nebraska, Arizona, Arizona State, Wisconsin, Iowa State, Kansas State, Purdue, Tennessee, West Virginia, Eastern Michigan, Miami (Ohio), Toledo, UNLV, North Dakota and North Dakota State.
As a junior, Wallace registered almost 50 tackles on defense, with 29 of them being counted as solo stops. He had 18 tackles for loss, 8.5 quarterback sacks and forced two fumbles, as Iowa City Regina advanced to the state championship game of the Iowa High School Athletic Association State Football Championships.
Future Minnesota Golden Gopher Has Been Key Two-Way Starter For Regals
Wallace also hauled in 40 passes for 611 yards with 10 receiving touchdowns on offense for the Regals. As a two-way player for Iowa City Regina during his sophomore season, Wallace had 27.5 tackles, including 16 solo stops, four tackles for loss and a quarterback sack, adding 51 receptions for 752 yards and eight touchdowns.
Back in March, Wallace announced seven spring visits to Notre Dame, Minnesota, Wisconsin, Arizona, Kansas State and Arizona State. He also visited Tennessee this past fall, taking in an SEC contest with the Volunteers.
Along with his success on the football field, Wallace helped lead the Regals to the Iowa High School Athletic Association Boys State Basketball Tournament this past winter. He earned High School on SI all-state honors in the process.
