Our mystery plant.
Well, this blog entry was originally to share details, benefits, and ease concerns about Chickweed (Stellaria media); a weedy plant I briefly researched a few years ago because the dogs like to nibble on various bits of greenery in the backyard, this one in particular. Our plant looked like it matched Chickweed photos, ours just had brighter yellow flowers. (Must be a Texas thing, right?!) However, better research shows I misidentified. Our plant is actually called Horseherb or Straggler Daisy (Calyptocarpus vialis). Misidentifying is an easy mistake, I’m assured by the blog Texas Herbs. By either name, our dogs seek it out and graze away, making the yard look as if an odd herd of miniature cattle invaded the yard. (Albeit squirrel-chasing cattle!)

The now-properly-identified Horseherb/Straggler Daisy makes its appearance in our yard every spring and late fall. It likes moderate temperatures and damp soil. Something we’ve had a bit of lately, so we are seeing an early, early appearance this month.
Took notice of this plant when the dogs were nibbling on it along with blades of grass. Concerned whether it was poisonous, I was originally relived to find that not only is Chickweed not poisonous, it is a plant actually sought out by human foragers and has reported health benefits. However, now that I know our plant is Horseherb/Straggler Daisy, not finding much support for its edibility. A bit concerning, as the dogs love to nibble on it and I tested it myself the other day to check the taste. Funny thing, it tastes as Chickweed is described, a mild baby corn or corn silk taste. Neither I, nor the dogs, seem to be ill after consumption. They have been nibbling on it for a few years with no apparent ill effects…though I wouldn’t recommend making a salad out of it based on this very unscientific study; certainly without proper toxicology testing.
Because your dogs may like nibbling on greenery, too, and it’s easy to misidentify this plant (pleading guilty!), here’s what you need to know about each one.
Horseherb/Straggler Daisy (Calyptocarpus vialis)
Horseherb/Straggler Daisy is both a valued US native groundcover plant and a reviled lawn weed, depending on its location. It attracts butterflies with it’s bright yellow flowers. Grows in southern US States.
An authoritative source of Texas plant info is the Lady Bird Johnson Wildflower Center. The Wildflower Center’s, Ask Mr. Smarty Plants feature gives a response to the question of toxicity. The following is excerpted from Ask Mr. Smarty Plants:
QUESTION:
Hello, I find horse-herb everywhere. Is it edible, too? Thanks!
ANSWER:
Mr. Smarty Plants hasn’t been able to find any information about the possible edibility of Calyptocarpus vialis (straggler daisy). None of the reference books listed below under “Bibliography” have listed it.However, we also haven’t found it listed on any of our favorite toxic plant databases:
Texas Toxic Plant Database
Poisonous Plants of North Carolina
Cornell University Poisonous Plants Informational Database
Canadian Poisonous Plants Information SystemThe City of Austin’s Native and Adapted Landscape Plants says that is “somewhat deer resistant”, which might indicate that it isn’t very tasty — at least not to deer. You probably wouldn’t get violently ill if you tried some (if it were deadly poisonous, I feel sure it would appear in at least one of those toxic databases), but you could possibly have some unpleasant reaction to it.
My advice is: Don’t try it. Since it is so very common, if it were really delicious, someone would have talked about it by now.”
Of course read the above advice after my taste test! More on this plant from the Wildflower Center: Calyptocarpus vialis Less.

Chickweed (Stellaria media)
This plant has a lot going for it! It’s safe to eat and used in various herbal remedies. It gets its name from its appeal to chickens and is even planted as a feed source for chickens and canaries. There are several types of chickweed and it grows all over North America. The flowers on this plant are white to light yellow.

While, I’m relived to know Horseherb/Straggler Daisy is not on a list of toxic plants and Chickweed is fine to eat, maybe I’ll just put “salad greens for dogs” on the next grocery list!
