    I have 3 aquatic plants growing in my ponds. The 1st plant is a great oygenator and a fantastic floating water plant. I don't know if it has a flower for it hasn't bloomed as yet. The 2nd plant floating amongst the azolla is a floater and its leaves are fuzzy and is very delicate. The 3rd floater has very tiny lily-like leaves and can propagate by runners. If anyone could identify them, I'd be mighty happy. Thanks!!!!

    The first one, Hydrocotyle, is quite a pest, covering the entire surface of pools and ponds with a solid mat.

    The third plant is European frog-bit (Hydrocharis morsus-ranae) of family Hydrocharitaceae. It is one of the monocotyledonous waterplants. The whole plant is floating. It flowers unfrequently but for distributing itself it possesses regeneration units, or gemmae at the ends of runners. It is native to Eurasia and is thus an invasive weed in North America.
