Floating Primrose


Recommended Posts

Last summer, I added wild caught Duckweed and what Google identifies as Floating Primrose  Ludwigia Peploides to my pond and windowsill.  The windowsill plant grew and bloomed over the winter until I accidently let it go dry.  I thought the pond plant was gone until I just found it blooming among the Peppermint.  Like the mint, this plant is said to be invasive, and that is probably true.  My sample was collected from the exposed tip of a sunken log in the middle of the lake.

Has anyone tried to grow this in the aquarium or pond?

I have not used this in aquariums. However a few years ago I bought seeds to sprout and transition to submerged growth because what I had read on it said easy to seed propagate and the seeds of this strain do not need stratification or scarification after dropped from the parts that flower above the water and that it does very well submerged with enough light
 

Sadly my eBay purchased seeds never sprouted so I did not get to try it.

I 'm having the same results from the Top Finn bulbs I picked up as an impulse buy. 

The plant pictured was about a two inch cutting when dropped in last fall.  I thought it had died.  Now it is almost outrunning the mint.

My pond is having a stranger than usual season. The Primrose was added as part of an experiment, to help eliminate the algae and other pond scum naturally. The peppermint did a great job of covering the water surface, and then escaped into the surrounding plantings. The Horsetail  that has remained in check for years, has now left the streambank, climbed up the waterfall and extended its range to four feet from the streambank.  It has never grown on dry land before so I suspect it is still feeding off of the roots still in the pond.  The primrose will probably do the same thing.
