in water

I'm happy with my arrowhead. Roots have reached the bottom of the jar already. Next to it I'm starting a new growing project- sweet potato vine. Had this idea in the back of my head for years, but I never tried it before. It took a lot of picking through to find a red sweet potato with some eyes on it at the grocery, but it might not sprout (they're commercially treated to prevent sprouting). If this one fails I'll look for an organic one.
