This is Dollarweed, aka Dollar Grass. I keep looking for some reason to like it, for some
neat bug that uses it - something to alleviate the aggravation I feel
when I can't eradicate it! Nope, so far it's just a vile weed.
I have noticed that it likes to be wet. Sprinkle a little less, and it
Then it rains...
Usually Dollarweed in my lawn is small, probably because it gets mowed
before it can grow this large. I found this one growing elsewhere, and
had to take a photo because I'd never seen one so big. Wow!
There is another plant that grows down here in Florida that you might
confuse with Dollarweed. It's Dichondra repens.
There's also a very similar wetland plant.
I found this
where Dollarweed (called Dollargrass there, and Pennywort
elsewhere), is bothering
other folks too. Julie suggested to Ragley that applying an herbicide
with a brush on just the Dollarweed might be another way to combat it.
I'll give that a try.
Since we're on the subject of which one we have, I've discovered that
there are several kinds of Dollarweed. Does anyone know how to tell the
difference between bonariensis, umbellata, and verticillata? According
to the Atlas of Florida
, mine could be any of the three. When I get around
to it, I'll look it up more carefully; in the meantime, if you know how
to tell them apart, please
Here are the small white Dollarweed flowers:
That dot in the top left
corner is a fuzzy fly (it was moving), which so far is the only type of
bug I've seen enjoy the Dollarweed.
