Grrr ... Almost impossible to get rid of this stuff here in my Florida lawn, we've been fighting it for years and I'm so tired of trying to eradicate it, especially from the flower beds. The runners break off when you try to pull them out and even when digging them, there always seems to be parts that stay buried to re-sprout within days (or is it just hours?)
I'm about to give up entirely and just go with a Dollarweed lawn!

This plant self seeds; for I have not planted it.It appears biannually ;thus someone planted it before I bought the house.(Last year it wasn't there) The leaves are thick in nature thus must consume alot of water.The flowers(white) sprout in the center of this thick leaf; (I never have seen this before).The characteristics of this plant suggest an Aquatic Nature(Which perplexes me since this area leans towards a drought!)

This is a very invasive little plant. We bought a small pot and placed it in the stream that connects our two ponds. We thought the long tendrils and small round leaves were very charming. This fall when we were closing down the ponds for winter, we discovered that those tendrils had rooted all throughout the stones lining the stream bed and were impossible to remove from all the tiny crevices. I was hoping the winter cold would kill it, but I fear this winter has been too mild. I'm going to have to work hard to remove this plant to keep it from clogging up our stream this year. Be diligent and cut off any tendrils.

I'd like to know how to eradicate this pesky plant. It has a delicate root system that breaks below the surface when the plant is pulled out. Digging the roots up isn't much help since some roots remain hidden in the soil to sprout more leaves. It thrives in wet areas, such as beneath a spigot or where marsh-like conditions exist, and looks messy among desirable plantings.

I found this plant on the edges of a bog near the sea, growing spontaneously. I don´t know if this is native to here, but this is quite an ugly little plant that seems to take over the places where it grows.
