I think you might be successful this time. Sometimes plants set seed that don't fully mature and develop, though. I tried to find images for comparison of fruits / seeds for Wasabia, but didn't get anything that satisfactorily showed relative sizing.
Thanks for your words. Thanks for searching information on line for me. That is so kind. I am expecting this for years. It's so excited. I can't stop to take photos for the seed pot.^^
I didn't find any picture of wasabi seeds pot as well for long. Today I found one. It's from a Taiwan's website. 阿里山葵 @ Sweet Time 義式手工冰淇淋 :: 痞客邦 PIXNET :: Picture is here: http://pic.pimg.tw/stgelato/4bf14c64bf4dd.jpg It's really like mine. ^^
