Help with a yellow flowering plant

No photo unfortunately as I was out running. But I came across a tall (4 foot?) plant which I had figured was a willowherb, and chalky moderately dry ground. Similar structure and appearance to rosebay willowherb and lanceolate leaves. But today it has flowered; a big spray of yellow flowers. Any suggestions as to what this might be? I know I should hold off posting until I can go back to get a photo, but it is bugging me.

The two yellow flowers that are in bloom around here just now are evening primroses, but they have large showy individual flowers, and the last of the golden rod. The golden rod has stems and leaves much like willowherb and it does produce a spray of flowers.
The native one is also called Woundwort, but it's not the purple one.
It's


I use it as a dye.

Now I'm confused :(

Whereas I accept that the plant Suffolkrafter has seen is, in all probability, Goldenrod (Solidago virgaurea), that link of yours @Toddy doesn't look anything like the Goldenrod I know; are they sure they've used the correct photo?


As well as the yellow dye that Toddy uses it for it has a wide range of medicinal applications, in particular for fungal infections.

I would be careful with the id. I deliberately mentioned canadensis as the are quite a few garden escapees, some of which might be toxic.

Really? In my research I haven't found any Solidago that is considered toxic to browsing animals or humans - in fact the contrary (as far as medicinal use is concerned). I'll have to do more digging (excuse the pun :)).

Geoff Dann's book lists both species as edible. The site I linked to earlier describes Solidago canadensis as containing pyrrolizidine alkaloids. I'd be interested to find out more.

At least in Finnish Solidago virgaurea is considered slightly toxic but still used in small amounts.

Many plants contain pyrrolizidine alkaloids that protects them from insects; in very small quantities it is found in teas and even honey. I would avoid eating any plant that is known to containing it because you don't know the dose you are eating.

Geoff's book is the only one I have found that describes Goldenrod (S.virgaurea or S.canadensis) as edible. To date, I have found no evidence of it being eaten in Britain so it's not on my edibles list.

S.virgaurea:
MedicinalConstituentsUtilityOther notes
antioxidant, diuretic, astringent, antidiarrhoeic, vulnerary, anti-inflammatory; remedy for urinary tract disorders, nephritis, cystitis, used to flush kidney and bladder stones, the saponins work against Candida fungus (thrush), taken for sore throats, nasal catarrh; leaves expectorant and anti-inflamatory, used to heal woundssaponins, diterpenes, phenolic glucosides, acetylenes, cinnamates, flavonoids, tannins, hydroxybenzoates, inulinflowers and leaves produce a yellow dyeuse flowering plant summer and autumn

Now I'm confused, because that make three varieties I know of all called Golden Rod.
The Canadian one which is invasive, with showy sprays of yellow flowers. The European one that grows like the fireweed and throws out sprays like that site shows, and the third one, also European, with sort of individual flowers but clusters of them almost like an aster. The leaves grow among the flowers in that one. I think it's also known as Himalayan golden rod.

They all give dye, but the European one with sprays gives the better colour. The latter one is the one picked for tea/ointment.

Interesting about the honey, I guess the bees must accumulate it via the nectar, depending on what plants they are tending to.
It won't be on my edibles list either.

The Solidagos are not native to Europe but were introduced from North America about 250 years ago, leastwise that's what the references here in France state.
Same family as Asters.
