Don’t be ashamed, the only stupid question is the one that you don’t ask. I wouldn’t have known that off the top of my head either and by putting the picture out there I’ve learned something new as well.
How would one go about extracting the dye from the plant? Is it a case of boiling up the right parts, or is there more prep work involved?It's weld. Reseda luteola.
It's one of the trio of native natural dyes that make pretty much any colour.
Blue from Woad
Red from Madder
Yellow from Weld.
They're all strong enough to cross dye properly so you get the entire range of colours; with care
Weld seeds prolifically but likes exposed areas where it doesn't face any competition while it's in it's first year.
Second year it goes up like a rocket
Pigeons love the first year plants and devour them.
Often found in the tracks of old building sites.

No need to ask a mod to do that, you have the power to do it yourself by clicking on the Edit button on your original post< Can an ADMIN amend my Thread title and put in ' Weld ' so future people can find it more easily.
Does the mordant alter the hue at all? If so, do different mordants affect the hue in different ways?It is one of those dyes that does awfully well with mordants. So, Iron, Alum and Copper....anyone who uses Chrome or Tin is not really being environmentally safe or friendly.
Copper's easiest, just put some pieces of copper into vinegar or ammonia in a jar and leave it for a day or so.
Iron, just break up an iron tablet in hot water.

Good info, thanks.Yes, they do.
Alum gives bright clear colours, copper gives green tones to the colour, and iron saddens a colour, but really fixes it.
There are also plant derived 'fixatives' which are really mostly adjustants. Rhubarb roots, or leaves, boiled up and the resultant liquid works well as to stop colour being just a slow fading stain and actually stay as 'dye'.
