Grocer to Garden - Lemongrass, Ginger, and Taro (part 3)

Grocer to Garden is a running experiment, taking produce from the grocery store and testing out techniques to propagate them into plants. The first candidates are lemongrass, ginger, and taro.  This is the third update, you can see the rest of the story here.  Commentary to follow, here are the pics.

Lemongrass

Ginger

OK, so it was 20 days under soil, but that's some nice growth.

Taro

Hassah!  Looks like the more submerged corm has taken a big lead.  The other bud which revealed in our last update hasn't grown much, but much more lies beneath the surface...
