A nasturtium - which has edible flowers and seeds (rather peppery taste).

It is a nasturtium. I have never eaten the seeds but flowers and leaves make a good addition to a salad.

It is an annual, Kate, so if you want more for next year you need to collect the seed.

I think the seeds can be pickled.....called 'poor mans capers'

That is interesting Pamg. They do look a bit like capers.

thank you everyone..my brother gave me seeds we didnt know what they were..well how interesting my husband is a chef so maybe he could use some for our salads :)

This link says use fresh unripe seeds Kate. Lucky you having your own executive chef. https://sites.google.com/site/atableforruerecipes/pickled-nasturtium-seeds-or-poor-man-s-capers
