Hello and welcome to GOY

Could they me anemone?

Sorry I've never had Anemones..

Are they not Slow release capsules?

No they are most definately not, I never use them, and one pod has split and a green shoot is showing. I have planted 5 in a pot to see if I can identify them, but takes soo long.

I was thinking that they looked like Nasturtium seeds.

So did I, T, but they are usually more ridged? But the fact that they were on top of the pots makes me think that's what they could be.

Before I scrolled down and saw your answer, Tug, I was thinking "Nasturtium seeds". I think these aren't dried out, Ojibway, which is why they don't look so ridged. Did you have any nasturtiums in your baskets last year, Shill1?

Sorry no Nasturtiums. Funny though everyone I show say the same. The only plants I had were Geraniums, Million bell Petunias,Begonias & Lobelia. The compost was new and came from different stores except for 1 which had old soil. I am wondering if the Million Bells could be the answer if they are from the Nasturtium family I also had a few double Busy Lizzies.

Even though you didn,t grow nasturtiums, the seed could have been dropped by birds, they certainly look like nasturtium seeds to me.

I have found over 20 of these in different pots seems a lot to me for the birds to have dropped. But I suppose anything is possible in nature. None of my neighbours have grown Nasturtiums so I don't know where they would have got them from.

Million Bells are more like a miniature Petunia, Shill. but none of the things you mentioned would have a bulb. If those were tuberous Begonias, a few bulbils could have formed where leaves touched the ground, but I wouldn't expect very many of them.

they also look like the remains of sycamore seeds that have had the wing bit torn off. I have a squirrel that 'plants' just the seed end of sycamore. it is so annoying.

million bells are not nasturtiums either.
how big are they. looking at the weave of the cloth they might be too small for nasturtiums.

Are they hard or corky?

They are hard and different sizes, funny to say but they look like little brains. They are also quite shiney. They are a lot bigger and fatter than sycamore and they were sitting on the soil not buried in it.

You could let some germinate, standing by to pull them out if they turn out to be weed seeds. I'm not hopeful that they'd be anything good, but it could be worth a try.

I found 2 sprouting in the garden this morning, I shall keep an eye on them..I do hope they are not weeds. They are not Nisturtians I have seen a pic of them and they have stripes mine have not. Thank you all for your interesting take on my query.

I wonder if they are a stone from a fleshy fruit [hawthorn?] that has passed through the gut of a bird. that would explain why they are on the surface and only just appeared.

the variegated nasturtiums dont produce stripey seeds. It wuld be wonerful if they did, then I could easily sort them out. :o)

I've just remembered what they look like - I think they may be seeds of a rush that you get in some composts. When you've overwatered a bit they germinate and you get a bog rush popping up in your flower pot or planter. Did you have a hollow-stemmed grassy thing that popped up out of the blue last summer?

I never had anything like a grassy stem, & there are too many to have passed through a bird. But just to add to the intrigue, this morning I found 1 pink & 1 red one.Weird or what?

is there a pyracantha/cotoneaster/rowan nearby? their seeds are about the right size [after the fleshy coat has been digested]and will be produced in large numbers.
when you get some seedlings post them for a better idea. One blackbird will eat 20 or more at every sitting.
