What do you reckon to this 'wild flower'

Forgot the pic ?

Oh dear I think this may be the dreaded Himalayan Balsam that is is spreading like wildfire throughout the countryside and choking native plants. Get rid of it now or it will take ver your garden. I would post a link if I knew how but if you Google you will see some clear photos.

There are quite a few different species of willowherb so I think you might be right on that. Will check my books.

It's not Himalayan Balsam. That looks like this (in the shade but they grow in full sunshine too. Bees love the flowers so I'm not so opposed to it as Imight be otherwise.

Anyhow, biologically speaking all species have been invasive at some point in their evolution so what's new? We worry too much sometimes.

Definitely not Himalayan Balsam

The leaves are wrong for willow herb.

Pic of Great Willowherb I took in Derbyshire early August and a couple more of H.balsam

Yes, the leaves puzzled me a bit too, merlot. They look kind of minty.

But the flower's wrong for a mint.

Whatever it is , it's quite nice, Bluebelle.

Thanks Baggs I like it it's pretty I don't think it's invasive there are two very distinct plants but they ve just grown and flowered and don't look as if they have spread the flowers are not like that balsam Tomorrow in the daylight I ll take a close up of the flower and a leaf

I just did a Google search of the image (which I didn't realise I could do) and Google's best guess is the Himalayan balsam.

It looks as though it has four heart-shaped petals. Is that right?

It looks like monkshood but that's usually blue.
I see a lot of it along ditches here.

I thought the leaves looked like mint too.

It's definitely not monkshead I know that one and it's definitely not the balsam flower yes Eelegran it has four heart shaped petals
The leaves do look like mint but it isn't mint, wrong flowers and no smell

Is it in any of your neighbours gardens? Could it be a self seeded cultivated plant?

That's what I was wondering, Nfk. The flowers are campanula like but not the leaves.

My thought too, definitely campanula-ish.

I think it may be calamint

What do you think, apparently there are a huge number of different roots of calamint

I wondered about calamint. The leaves are right but the flowers are wrong.

Is there a prize?

It's very pretty whatever it is!

In the photo against the wall it looks like long seed pods below the flower on the right. That reminds me of willowherb. I think it's this one:

The one against the wall isn't my picture Tricia
Here's a couple close ups unfortunately we had a lot of wind and rain last night so it's not looking too perky
There are actually 8 petals which lie to look like four heart shaped petals not so obvious in this photo as they were a bit dashed out of shape
