Dichondra carolinensis Michx. is the correct and accepted scientific name for this species of Dichondra. It was named and described as such by André Michaux in Flora Boreali-Americana in 1803.
The genus, Dichondra J.R.Forst. & G.Forst, was named and described as such by Johann Reinhold Forster and Johann Georg Adam Forster in Characteres Generum Plantarum in 1776. Johann Reinhold Forster was the father of Johann Georg Forster.
As of 11-17-21 when this page was last updated, Plants of the World Online lists 15 species in the Dichondra genus. It is a member of the plant family Convolvulaceae with 59 genera. Those numbers could change as updates are made on POWO.
The above distribution map for Dichondra carolinensis is from Plants of the World Online. Areas in green are where the species is native and purple where it has been introduced. The map on the USDA Plants Database is somewhat different… I have no clue where POWO obtained the data for their map. In Canada? Hmmm… You never know…

I lived at a mansion in Mississippi for several years, and in 2010 this viney plant started growing in a pot of Aloe maculata and a little in the back yard (behind the pots). I thought it was neat. I identified it as Dichondra carolinensis since it is the only native Dichondra in the state of Mississippi. I lived at the mansion until February in 2013 and it the Dichondra didn’t return after 2010. It disappeared as suddenly as it appeared…
I always wondered how it came up in the pot in the first place. I mixed compost, wood bark, decomposed branches, and maybe some soil from the yard along with potting soil and put it in the pot. So, I think the seed was transferred to the mix. I never watered the yard, and since the pots were watered weekly during the summer I guess it triggered the seeds to come up. I thought it may have been because I watered the pots at least once a week, but some information online says the species prefers dry sandy loam…
The uses for Dichondra are varied and interesting. Some people plant it in their lawns while others fight to get rid of it. There are even a few cultivars available as they look really good in hanging baskets.
I have received a few comments asking where to buy seed of Dichondra carolinensis… Well, that is a tough one. I checked online and found basically ZIP. Dichondra argentea, however, is widely available and there are several online sources as well as on Ebay. BUT, that species is a native of Australia. SO, if you want a native species you might want to check with the conservation department in your state or perhaps a county extension office.
There are other species of Dichondra native to other parts of the U.S. Go to the USDA Plants Database, type in Dichondra (or click HERE) and you will see the list. Click on each name and it will take you to the maps. Zoom in closer over your state to find the counties the species has been found in. HOWEVER, who knows how old the maps really are. The USDA gets their maps from BONAP and they don’t always match… BONAP maps say 2014. Well, we are a work in progress.
I live back in Missouri now, and the Missouri Plants website says Dichondra carolinensis is a fairly new species for the state. It has only been spotted in a few lower counties. Many of the other states it is listed have only scattered populations in just a few counties.
