Do geums self-seed much?

The reason I'm asking is that i have some tame geums in the garden but I also have a geum urbanum problem.
Some of the gu sneak in beside the cultivars.
If there is little likelihood of self seeds, I will be able to hoik out any younguns that appear.
If not, I'll have to think of something else.

    The red variety I have seems to self seed alright and I remember someone commenting on a gardening forum how they would not grow Geum because they did self seed so much. I like the way they grow from seed so easily and have lots of them in the garden now as a result.

    I have several of the orange ones. Totally tangerine? Anyway, they don't seed at all and when I collected some seeds I couldn't get them to germinate.

    Thanks for answers. I've already weeded them out on a better safe than sorry basis. It's good to know you can get seeds for them, though. I didn't realise.

    I used to have well over 20 different forms of Geum. The hybrid types did not seed much, but the varieties really did. You need to dead head them assiduously to stop them from taking over, or at least we did. The worst one for self seeding was a pink one (name gone).

    I for one consider geums as a pest in my garden. I had a red one about 20 years ago. Removed it and now I still find it growing from that original seeds in odd places in the garden where they are duly removed.
