Excitement! Such a small piece. No stems have failed to take root for me after being stuck in a pot.
Moving water is a different venue than the stagnant water of jar, bottle, or vase. So many great pics over the years of folks propagating in an aquarium, with a bubbler oxygenating the water.
This is variegated "lucky bamboo." Stems growing well in a former wall light sconce. Started by just sticking them in there after filling the sconce with soil.
