Or not? I'm finding this a tough one to crack and am of course concerned about its family.
Hmmm.... Really need a bigger picture. Not sure about the leaf shape.
Is it just me or does that look like small giant hogweed. Difficult to tell.
This is normal hogweed.
This is the key for giant hogweed.
large plant, often over 2.5 m high (when mature)
flowers in umbel shape, larger than 15cm in diameter
flowers have more than 50 rays
hollow stems are between 3-8 cm in diameter
stems have stiff white bristles
stems have spots or blotching, red or purple in colour
large, lobed leaves up to 1m in size
leaves compounded in three
Oooo... careful pal. I think that may be giant. Please go give any skin you had in contact with it a very good wash and move it somewhere safe.
Stems have stiff white bristles, leaves compounded in three. Stems are green with extensive purple splotches and prominent coarse white hairs. Stems are also hollow, ridged and have a thick circle of hairs at base of leaf stalk.
Pops always warned me about giant hogweed, but I never realised how horrible the rash is from the sap...google it!
That aint no hogweed. thats cigaweed!
I'm no authority when it comes to hogweed, I've only been studying it a few weeks. Best be safe than sorry though until someone can 110% id it.
Are the bristles stiff? (use a pen and bin it). I dont like the leaf cluster (looks like 3 lobes) or the fact that the stem looks hollow. Can you safely cut one open to have a look. I would personally bin the cutting implement too and stear well clear of any liquids from the plant. This is why I dont collect unless its 100% confirmed before removal.
The hogweed I was looking at had very fine hairs, almost fluff and did not have the purple banding around the leaves that yours does.
Hmmm. I would rather be wrong than right.
The purple splotches mostly occur on the main stem.
those leaves look a little different from the giant hogweed I've seen.
Do take care - i've had a 'chemical burn' from giant hogweed on my ankle. The blistering was about 50p diameter, 6mm deep. The bruising travelled right through my ankle joint and appeared a few days later in my toes.
OMG, that is some bad stuff.....
The bristles are soft and the cross section is that of an old school Star Trek badge.
The more I look at it, the less likely it's hogweed, maybe there's none growing round here.
I've sent a few pictures to a mate to clear up what it is, so If you dont have a reply on here, he should be able to help.
Umbellifers are an interesting group, but not something one want's to get wrong in any way, shape or form.
That pic doesn't look like giant hogweed to me. The leaves of giant hogweed are very much more deeply incut, giving the leaves a very spiky appearance. Those leaves look much too broad. From the pics, I'd say ordinary hogweed is a fair bet.
You may be right... It was the bristles that alerted me and the purple tinge around the leaves.
And, it not looking anything like yesterdays hogweed. Best to be safe and all
The sap of Giant Hogweed contains chemicals that make human skin hypersensitive to the UV in sunlight, a condition called phytophotodermatitis. The resulting burns can be very severe. If it gets in the eyes it can cause blindness. If you should acidentally get the sap anywhere on your body you should get indoors PDQ! The same chemicals exist in many Umbelliferi but not at the high concentration of Giant Hogweed
It is not giant hogweed. It is probably normal hogweed but dont eat it for tea yet. The absolute utter diffifing feature of normal hog weed this time of year it that the young shoots curl inwards before unfurling, that have soft down on them.
Hogweed, giant hogweed, parsnip [including garden!!] and few others all cause rashes when the sap is on the skin and reacts with sunlight. Giant hogweed is by far the worst though. Generally the sap washes off quite easyly and it smells like roses when the reaction is occuring. Covering exposed skin for a few days also prevents quite a bit of damage. I regulary pick hogweed shoots and wild parnsip, just washing in a stream immedatly afterwards seems to work.
Thanks for your advice all.
That is hogweed (heracleum sphondylium) beyond a shadow of a doubt. I know the plant at a glance. They're the young spring shoots and some of them should still be just unfurling around now. I tried cooking them but they were awfully bitter. The stems should have coarse white bristles and the stems are often coloured purple towards the base. With the umbellifers, it's the ones with the really finely divided leaves that you have to be cautious with. Hogweed, once you get to know it, is easy to ID. Cheers
Cheers wilderranger that's great news.
