A neighbor gave me seeds to grow this plant, but I have absolutely no idea what it is; I've even done a web search. She hardly speaks English and cannot even write down the name in Vietnamese. It stands about 24" tall, only has 2 or three leaves at the bottom, and the top 12" has these 2" long thin pods that are very peppery; very similar to nasturtium. I would assume the pods are used in stir fries.
Thanks for your help!
