A few of us collected some local plants from the edge of a large pond earlier this month. This was one of them. At the time of collection, the pictured plant (actually several stems by now) was an inch high and emersed. For almost a month, we had no idea what it was.
I returned yesterday and found some small but incredibly vivid blue flowers. Thumbing through a wildflower handbook revealed it to be Myosotis scorpioides
It has absolutely no trouble adapting to submersed life. It looks somewhat like Hygrophila polysperma
but has a thicker stem, a chalky green color similar to Hydrocotyle sibthorpioides
, and a very unusual coiled leaf arrangement.
Please forgive the photo quality! It was taken under less than ideal conditions...
Without googling it, can anyone give the common name of this plant?
