I live a little to the West of New Orleans, in Kenner, Louisiana.
I have been growing Gotu Kola here for well over 35 years. I always winter a couple of plants inside when it freezes but it is now growing wild in my grass and garden as well. But a really deep freeze does seem to kill it.
If you live in a hot dry area try growing it in a 5 gallon bucket with a 5 gal. water jug with the bottom cut off on top. It doesn't like air conditioning much/ too cool and dry. The stems will get very long if the soil is deep in \ the bucket. It likes hot, sunny and humid. A local lady I know grows it in a wheel barrow and rolls the whole thing inside when it's too hot or cold. She uses lots of it in making tea and adding to salads. As earlier stated by others it's kinda grows like strawberries and needs room. I have found that when taken raw and for the fist time, a slight headache sometimes occur, as it is also know as a brain food or cleanser and I believe that's a cleaning out side effect, (my opinion). I also believe that it Is known in India and other parts as Hin Gotu Kola. It can also be found under 3 additional different Latin names.

This plant has become famous in the Philippines for its proven medicinal effects for arthritis and hypertension. . . People are eating 2 to 3 leaves a day to reduce arthritic pains. It also has sedative effects on others. So, if you're an insomniac, it is advised that you eat 2-3 leaves before going to bed. . . Gotu kola has become an almost cure for all herb. . . For me, it improves mental acuity. I just eat 1 leaf in the morning and 1 leaf before going to bed and I feel great!

This plant was once highly touted on the west coast as a means of preventing aging. It tastes much like parsley and is said to be high in B vitamins and is a diuretic. Easily propagated from daughter plants and grows much the same as strawberries. Easy to grow in the south from seeds started in the spring or fall. Needs bright shade and ample water and may be invasive in the south. Also known as Indian pennywort, elephant plant, and marshpenny.

Grows really well in Mayaguez, Puerto Rico. Needs lots of water but likes full sun. Can tolerate semi-shade. Needs space to grow better. Many people use raw Gotu Kola for medicinally purposes in salads or sandwiches (just a few leaves) and also make infusions from the fresh or dried leaves. Scientific researchs found that the plant improve legs circulation and memory.

Centella asiatica is a very wide rangng subtropical stoloniferous herb - from the coastal plain of the SE United States south through South America, and in southeast Asia, perhaps elsewhere. American plants are sometimes segregated as Centella erecta. It is very common on the coastal plain of the SE U.S. in a wide variety of moist to wet open areas, both in natural habitats and in disturbed or weedy areas. It is a common "weed" in my lawn but I really don't try to get rid of it, as the effort would be futile without lots of chemicals!

I found four of these at a local nursery, but they could not tell me much about them. Three wintered well in the winter greenhouse sitting in a bird bath full of water but was a bit leggy in spring. One wintered in a birdbath outside in speckled shade, also in a bird bath full of water, and was much more compact. Supposedly highly valued for it's medicinal factors. Growing information is scarce. Aka Asiatic Pennywort or Spadeleaf. Tendrils grew into the water and started roots.
This plant has been said to grow in the following regions:
Budapest, Berkeley, California Merced, California Bunnell, Florida Fort Lauderdale, Florida Pembroke Pines, Florida Sebring, Florida Kenner, Louisiana New Albany, Ohio Mayaguez, Puerto Rico Plano, Texas Spring Branch, Texas
