Cosmos self seeded

I was just having a look in the garden and saw that in one area I had a whole lot of self seeded Cosmos - what a lovely surprise. As Cosmos is a tender annual, I rather assumed that it wouldn't self seed. Is this normal?

 

Yep. Completely normal. I always leave the last seed pods on to self-seed. They're a bit slower than if you start them off in a G/house etc. I find they self-seed in a small area and I just shift them about to where I want them:wink: It's a bit like letting Morning Glory self seed. Free plants, Yeah!!:gnthb:

 

Thanks Cajary. I don't get a lot of stuff self seeding except for a usual old lags - forget-me nots, Centranthus and Verbena bonariensis. But I fairly rigorously weed them out, and I suspect a lot of other stuff goes as well.

Come to think of it I probably don't leave the parents long, in the autumn, after they have gone to seed as I need the space for early flowering biennials for the next year.
