Solved Am I growing another weed?

Hi everyone, I've be growing this for a few months I have a feeling it may be another weed can anyone tell me for sure, the yellow flowers are very tiny and in clusters thanks.

 

Your plant may be stunted growing in that pot, but Google image search 'Ragwort'.

 

Nice yellow flower.

 

And much liked by butterflies, such as Common Blues and the leaves by Cinnabar Moth catterpillars

 

It seems that lots of people, including many of those who keep horses want to make Ragwort extinct, but it's also a valuable plant for wildlife:

What can happen if uncontrolled

What it all boils down to is about striking the right balance, unless you have grazing horses in your garden in imminent danger of death, it's probably safe to leave it for moths and butterflies to enjoy.

 

@Scrungee, crikey I can remember two or three of them growing many many moons ago covered in those stripey caterpillars, I think I'll keep it, no chance of it taking over the concretes already done that.

 

Looks like a crucifer (mustard/cabbage family) weed to me. Wait til the flower emerges properly: if it's a daisy-type thing then ragwort, if 4 petals then a mustardy thing like charlock (there are loads of species). Same conclusion tho: weed!

 

I have Ragwort in my garden and now have both blue butterflies and Cinnabar moths . The Cinnabar catapillars destroy the Ragwort plant they feed off but Ragwort does self seed very easily. I don't like to use chemicals if I can avoid it. I found cutting a Ragwort plant back to ground level and covering it with an air tight and light omitting black or very dark receptacle such as a box or flower pot will kill the plant after several months. Not a quick solution but more environmentally friendly.
