Looks like fox and cubs....Heiracium (which is a hawkweed)

I agree, so people do grow it in the garden as it is such a clear orange.

But it does attract blackfly.

And is an awful thug both from seed and runners.

Orange Hawkweed. A pretty flower in the garden but invasive.

Gawd don't give it space in your garden Bulba. did in our lasr garden and it is still there in spite of being weeded out many times!

It was a nuisance in my previous garden, but in this one it doesn't spread. I don't know why, but I've got just one plant, and it's been there for a few years. It doesn't seed itself around like it did in the other garden.
