The tip of the sprout got kind of stuck in the potting mix when it germinated last year. It eventually found its way out of the dirt, but by then, the stem was already twisted and I didn't want to try to straighten it out too much out of concern of breaking it. That happened to 3-4 seedlings. With some of them, the new growth on second leaf (this year) was from the base, with others, from the tip.
