https://files.catbox.moe/e1tubw.jpgBought 3 sets of live Wasabi plants a couple years ago from a grower a bit south of San Francisco. First time they've flowered. Still in the one gallon pots, so probably time to separate the multiple rhizomes, harvest a few, and repot the rest.
So far the only pure Wasabi I've had is the freeze dried, so am anticipating my first fresh. You never get actual Wasabi at your sushi place. It's mainly horseradish and chemical dyes.
If you garden, the starts are very affordable, and they multiply off of the main rhizome. The initial 3 sets could become 24 separate pots now.

After winter and before summer heat is probably the best time for shipping.
