3 MORE Dangerous Flowering Weeds to Look Out For

A lot of times it’s easy to spot weeds in your yard. Some have imposing jagged-edged leaves, or furry foliage. Others have thorny stems. Many times they stand out simply because they tower above other plants in your garden. Most times, though, they’re noticeable because they’re just plain ugly. Either way, you know you didn’t plant them, so they don’t belong. 

There are times, though, that weeds can make themselves pleasing to the eye by producing pretty flowers. Their flowering buds, however, can’t often be trusted because pretty can also be pretty deadly.

Below, we discuss three more of the most dangerous flowering weeds to look out for in your yard.

Water Hemlock

Don’t be deceived by water hemlock’s clusters of lacy white flowers that top its wiry branches. There is nothing dainty about this vicious weed. Water hemlock contains a toxin known as Cicutoxin which can cause severe seizures and convulsions that result in cardiac arrest and death. The USDA even classifies it as the most violently toxic plant in North America. So be super careful not to confuse water hemlock for wild parsnips, or other herbs.

Giant Hogweed

Giant Hogweed is a plant that will get your attention. Aside from the fact that it can reach up to 15-feet tall, it has huge blooms that somewhat resemble a super-sized version of Queen Anne’s lace. There is nothing understated about giant hogweed.

Keep your distance from this intriguing and deceptively beautiful plant because one touch of its sap can result in extreme skin irritation, burns, scarring, and even blindness. Don’t try to remove it from your yard. Contact the environmental agency in your county as soon as possible.


If you’ve ever heard of poke sallet (salad), you may be familiar with the poisonous pokeweed from which it’s made. We know that salad and poisonous sound contradictory, but here’s the thing: when properly cooked by chefs, which involves boiling pokeweed leaves in water up to three times until the water is colorless, toxins in the foliage become latent—making the leaves a main ingredient of this Southern dish. 

But don’t underestimate the toxicity of this plant. 

If pokeweed leaves aren’t properly cooked they can quickly induce vomiting, diarrhea, convulsions, and rapid heartbeat in those who consume them. Check your yard for this unmistakable weed. During the growth and maturation process pokeweed changes from green to bright magenta stems, and has tiny white flowers that develop into green berries, which ripen to a dark purple.
