I lowered the water level and poked around in the small tank that I crammed the largest plant into, and came up with a new bloom just below the surface, as well as at least two swollen pods under the water. I'm relieved that I'll likely have seed for next year. The geodesic cross-beam reflections are a bit distracting in most of the pictures I tried to take, but at least this one shows off the new bud well.
