Giant Hogweed Identification and Comparison with Cow Parsnip 

EXCEPT, no mention of purple, raised spots or streaks all over the main stem, and minor ones.

Supmah Gaming what about fire?

@@NotoriousN_I_G_ no!! Do not burn these plants. That’s a terrible idea. Imagine what the sap would do to your insides if you inhaled it.

@@_P0tat07_ nothing it is phototoxic

Cows Parsnip is a small look-alike and common in gardens. It is not hogweed plant.

And evidently downwind.

The danger is greatly exaggerated. The people of the city are so afraid for their lives, it's like they've been going to stay here for 1,000 years.

@@uldymuldy I have a scar on my hand from when I touched one when I was nine, and I had friends who were similarly affected. I think the big issue is really that they might accidentally get ingested, because there are other hogweeds which are edible. They're also very invasive. There was a patch of land near my childhood home which got taken over completely by giant hogweed and Japanese knotweed, and it put paid to the biodiversity there. Not necessarily a danger to humans but still regrettable.

@@nineteenthly It's sad to hear. Why not neutralize with sodium carbonate? Why touched?

@@uldymuldy I was a child at the time so neither would've occurred to me. It isn't actually something other apiaceae are exempt from. They all contain the psoralens which have the effect, and if you happened to have an opaque glove or something else to cover your skin immediately after touching, you'd be fine - you could just go somewhere and rinse it off. But I know I get the tingling and numbness from celery too, so maybe it sensitised me to it.

Just the sap. You have to break the plant and get the sap on you to have the effect. (it is NOT an oil on the surface of the leaf like Poison Ivy is) ...that said hogweed does have prickly hairs that could get embedded in your skin and cause irritation...

They have recently come to southeast Wisconsin, apparently. So you might be able to see one there.

Thanks for sharing, it makes sense, the psolarens change our cells DNA structure: when damaged by burning, they get replaced faster, but it can take years. I cut a few flowers/seeds a while ago for avoid them spreading without wearing a mask and likely the splash made my face's skin very sensitive to sunlight, even when using suncream.

wild parsnip is another one too that can be troublesome. Luckily its easier to control.

Are you aware of the green 3-5 feet think plant, contact with it feels like a burn, no pleasant?

The sap causes the initial damage. Anywhere the sap touches the skin, the UV protection is wiped out. Subsequently when exposed to the sun the skin will burn severely and permanently. Beware the vulnerability to sun will last for several years. Also if the sap get into the eyes - blindness can occur.

So the cow parsnip sounds just about as toxic as does the giant hogweed if it wipes out UV protection and causes severe permanent burns from the sap.....unfortunate that you didn't have both species in flower for the presentation.

Does it negates the benefits of sunscreen as well?

I just touched the leaves of baby cow parsnip and the backs of my hands were itchy for days

Nope

If you're anywhere near Southern England it's found all over the place

Do you worry a bit? I removed one with gloves being careful and took a shower afterwards. Totally fine. The sap is only dangerous if the skin is then exposed to sun. If you wash off the sap then the danger is gone.

@@gerryp3628 I was speaking of the giant hog weed not the cow parsnip for precautions. Yes I have had small marks from exposure to both on my arm and my leg from touching just the leaves even after washing The sap is present on any cut portion and the underside of the leaf on both and in enough of a quantity that it will react instantaneously to any bare skin of you come into contact with it during a sunny day. You will break out on your way to washing yourself or shortly after.

They are now considered people

There is only one gender. The human gender.

It simply the Largest Herb you will ever see .. Plants are divided into groups that's all ..Trees - Shrubs - Herbs - Vines -etc ...OK?

D-don't burn it 0-0 it will make you go blind!

There's lots of it in West Sussex where I live, it's all over the place

Have you seen this thing in person because it’s not about 2ft tall these things are huge

Listen to Mc Hammer!

OMG, America is infested with "Up Talkers" using the inflection of a question at the end of every sentence. It is so contagious, and because our education system is so fraught with Liberals, bending over backwards to please and not offend every single person that walks across the Border- that our children AND young adults do it, just as with an influx of certain Europeans, who over emphasize the suffix "ing" is very catchy to young minds- who are taught to never correct a mistake, that everyone "has their own way of doing things". 🤢🤮

Christine Newland if he wants to I guess he can but that will be his problem when he gets massive painful blisters when he accidentally brushes up against it.

He should not be allowed since it spreads easily and will continue to do so.... His plants could produce thousands more.

marianwhit seriously I didn’t know they were dangerous and was curing them barehanded and everything haha

Hogwash, I say-

She needs to speak loudly over the strong breeze.

Kredo800 Yes, there could be a hole species of hogweed with different features and control methods, using Latin makes it that much easier to identify them to the plant, bit you probably already know that!
