Well, this year I decided to let my aquatic utricularia overwinter in their ponds instead of removing and babying the turions. So I looked at one of the ponds the other day, and see U. macrorhiza (Plumas Co., CA) already growing. The funny thing is that they actually anchored themselves in the substrate at the bottom, and then grew about 2 ft. straight up before they finally reached the surface.
