Plant ID's Please.... again :)

Any help would be much apprecaited (this should help keep @Silver surfer's Alzheimer at bay )

1) A plant that was given to somebody as a Hollyhock a couple of years ago, but doesn't look like any variety I've seen. It can grow as tall as 9ft high but presently about 4ft. Looks a bit Black Mullein (Verbascum densiflorum) to me, but may be complately wrong.



2) A Wildflower which I'm guessing is Hemlock (Conium maculatum) but not 100% sure. Is about 4ft high. Smooth stems but no purple speckles.





3) Another Wildflower but have got the foggiest what it is. Was growing on a sand bank next to a sea wall. Was also about 4ft high. Was pretty sure it had small beige flowers a few weeks ago but has now gone to seed.





4) Wonder what this could be . It's Fallopia japonica of course and has spread about 200 metres in a few years along the sand bank and the sandy conditions seem to keep its max height to about 3ft high.The height though may indicate some form of hybrid.

I spoke to a guy whose house was about 10 metres away from it the worst area and he said he'd dug deep to get the roots out of the garden, soaked the rhizomes in bleach, then buried it. He says it never came back.... sure thing buddy! I bet he dumped it all in his green-waste council bin in reality - why on earth would you bury it again!?

 

Need to see some of the leaves to be sure, but I think number 2 is fennel.

 

Thanks mate for the reply. Unfortunately there were no leaves left, just bare stalks and yellowish seed heads.

 

Thanks @shiney.

Two confirmations of fennel seem a good enough diagnosis.

May take a small sample of seeds on the next visit as it's near my Mum's house and see if it grows into that superb veg.

 

1. Looks like Echium...such as Echium pininana.

Many thanks. As always, your knowledge of plants is truly astounding!

 

If the second plant has a scent of aniseed, it is Fennel, if not, it is Hogweed.

 

No 4....I'm pretty certain is Japanese Knotweed. The stems tend to have a zig-zag in them.

 

And to complete the set, No 3 is Artemesia vulgaris.

 

@ The 4th pic in the OP, which appearead to be Fallopia Japonica, may actually be Fallopia x bohemica. A hyrbrid of Jap Weed (Fallopia Japonica) and Russian Vine (Fallopia baldschuanica).

I looked closely at a lone plant that was approx 200m from a cluster which is right next to a Russian Vine.

This plant's flowers had turn to seed pods (a little like Shephers Purse/ Capsella bursa-pastoris in appearance), most of which had gone but I opened one up to find a small, brown tear-drop looking seed inside, which may explain why this solitary plant was so far away from the others.

Maybe a bird ate a seed from a plant in the cluster or it got stuck to somebody's shoes and germinated. I made sure my shoes and clothes slighly had nothing stuck to them and was tempted to take a seed but know that it would be a criminal offense, and way too dangerous to risk planting anywhere anyway. The fact that a Japweed plant that can produce seeds only a few hundred metres away from her house is worrying her somewhat.

Fallopia xxx.....This link may help.
It seems rather hard to id.
Need to have a good look at the leaves...size/shape/veins.

As far as I am aware, Japanese Knotweed is sterile, so cannot produce seeds. It can only spread by vegetive means, eg suckers/layering etc.

 

Thanks @Silver surfer .

I'm resorting to having to use a phone to browse as the laptop is a nightmare here.

The leaves are more rounded than the F. Japonica. They seem to lack the pointed tip of normal japweed and none of these plants are more than 4ft high. Maybe the sandy terrain is not to their liking.

There is no giant hogweed in this local area to my knowledge, so that hybrid maybe less likely, although can't be ruled out. The seed pods look very similar to a customer's garden I worked in today which has a Russian vine creeping all over her fence but it was awkward taking pics so will take some tomorrow at another customer's house who has the same predicament.

I'm near enough certain this is a hybrid of the two and will take closer pics of the underside of leaves and stalk this weekend.

@daitheplant

Japweed is seemingly sterile as there are no male plants in this country but it does indeed hybridise with giant hogweed and Russian vines to enable a plant that is in essence Japweed that can produce seeds. Although, the seeds (allegedly) can revert back to either parent plant and are not particularly viable. However, it only takes one japweed-orientated seed to cause havoc, without there being any transfer of rhizome necessary.

 

@Silver surfer

Here's some more pics. The original plant posted in the 4th pic of the OP was on a wind-swept bank and had kind of keeled over, but in its prime, was identical to the cluster of plants next to a Russian vine.
