In the home landscape, the problem is magnified because the use of herbicides (whether chemical or natural) is difficult to direct only to the offending weed. Dried buttercups are not poisonous, so if this plant is harvested with hay, it does not post a problem.īecause of its seeding and creeping methods of reproduction, buttercup is extremely difficult to control in field and pasture environments. Horses, sheep, and pigs are also prone to poisoning, but not to as great a degree. In severe cases, colic can progress into respiratory distress and convulsions. A cow with buttercup poisoning will give less milk, which will be bitter and tinted pink. Livestock are especially susceptible to buttercup poisoning from grazing, with cows being the most often poisoned.

Once this plant establishes itself in your landscape, it is very difficult to eradicate and, because of the creeping habit, it can quickly crowd out all other plants. Most Buttercups spread by seed, but Creeping Buttercup spreads by stems which root at the nodes. The flowers have 5 or more petals, and grow on long, hairy stalks they are usually bright yellow and shiny, although some white is documented which is related to fading with age. The finely- palmate, alternate leaves are quite attractive, often with light mottling on the dark green.

In the wild, you'll find it growing in ditches, along roadsides, in vacant lots and lowland pastures, or any area that remains moist. The USDA Plants Database shows this species as being naturalized in all areas of North America except Florida, Puerto Rico, Georgia, Louisiana, Oklahoma, Kansas, New Mexico, Arizona, North Dakota, Saskatchewan, and the Northwest Territories. Mike Hunter of CCE’s field crops team did a quick check of corn herbicides with this weed listed on the label, and found Banvel (and many other generic dicambas), Diflexx Duo, Distinct, Fexapan, Roundup Xtend, and Xtendimax.Creeping Buttercup ( Ranunculus repens) is one of the most aggressive wildflowers in North America, thought to have been imported as an ornamental from its native Europe. Purdue University produced a good summary of agricultural control of buttercup through herbicides. ManagementĬontrol of creeping buttercup can be obtained through regular cultivation in drier conditions, repair of the drainage in the infested field, spot pulling or spraying, and herbicides. Most of the information available is from the Pacific Northwest, such as this article from the state of Washington.
It is not toxic in hay I did not see data on its toxicity in wet feeds such as sileage. While it is not very palatable, it’s reported that occasionally livestock develop a taste for it and injest fatal doses. It’s a perennial that’s often found in wet areas of pasture, farmland, or roadsides. There are several weedy buttercups, but this one has three lobes on it leaves and aboveground stolons – aboveground runners – that it uses to spread. This is creeping buttercup (Ranunculus repens).
