Nastursions

Well. a couple of years ago I had a lovely show of nastursions which produced lots of seeds. Maurice advised putting them in a plastic bag in the fridge and they would be fine. I discovered them when i was having a bit of a clearout a few weeks ago. On the basis they were getting a bit old, I chucked them in a tub. This is the result so far. I wonder if they will flower or if it is too late?
