I found some seeds my mom had after she passed recently. SHe called it nin choi but I found out its a strain (species) of Amaranthus. I don't have any photos of her nin choi but I have a picture of the seeds. Could anyone help me identify it? I would like to buy the seeds again and plant them.

The seeds she left behind are so old they won't germinate!
