Seeds 4mm diameter
Description:

Does anyone know what species these seeds belong too? They are 4mm in diameter and came from an annual vetch of some kind that I found growing in the south of France many years ago. I have long wondered what they are and Valentine's Day seems a very good day to find out.

Grow some?

Have you tried growing some? The whole plant might be easier to identify.

You are right and I did try

You are right and I did try that years ago I think but they didn't germinate. I ought to give it another go. Legume seeds have hard coats and last a long time, so they might still be viable. I don't want to use too many of them up though. They are such curious little things!

Same plant family, but otherwise not I should think.

for germination...

...some tough seeds need to be nicked - perhaps you could try this with one.

You are right. Sandpaper does a good job.

Cardiospermum halicacabum

Looks like a good ID but the spelling above seems to be the one recognised by iSpot.
