This plant may be hard to recognize because it will change when grown submersed. From my experience, it appears that many people sell this plant immersed. It is more curvy and has blossoms as an immersed plant. When I won some of this plant on eBay I thought the seller either sold me the wrong plant or scammed me. Quite a bit of this plant did not make it during the transition process in my tanks. Quite a bit of it rotted, but half of it survived and what did survive is doing very well and it was fascinating to observe the physical changes in appearance over the course of about three weeks (from immersed to submersed). I love its succulent-like appearance. It is a robust plant that does well in medium/moderately lit tank setups.
Bacopa Monnieri is also known/sold as "Brahmi" aka the memory herb. In Ayurvedic medicine, they say if you eat 10 leaves per day it acts as a type of tonic for the brain and increases memory function and mental capacity. I grew mine in a coir hanging basket where it did fair-average. I rinsed it all clean and put it into my aquarium and it has thrived ever since. A fantastic plant for most aspects of the aquarium, and very hardy due to the fact that it normally grows in boggy/marshy areas in it's native habitat. Will also grow small blue coloured flowers when emersed.
Okay first off "Difficulty: Medium"? I don't agree with that one what so ever! I have found this to be one of the easiest aquarium plants to grow, something like Wisteria..So as far as being difficult, I have kept this one in a jar beside my window for many years and with out any ferts, grows great. Also I this one easily converts to either submersed or emersed easily and doesn't even lose it's leaves under water. if grown in natural light it will stop growing in Winter, but resume in Spring. Cut it once it gets to the top and plant densely or it will become a tangled mess. Great for sucking up nitrates and NH4 fast, and is also used in fish farms to keep water clean.
Got a little one inch sprig about a year ago with a few fish i think, it is now in about 6 four inch stems. Grows slow for me, but refuses to die. Excellent green color, almost as bright as my apono cf. ulvaceus.
Great, easy to grow plant in my experience with it. I had some growing above water in my pond and just tried it as a submersed plant in my aquariums and I love it. It rooted very quickly for me and is growing very fast. Beautiful flowers grow on plants above the water. I really like how easily it transitioned to growing submersed without losing their leaves.
According to the USDA, the native range of Bacopa monnieri includes that of its cousin, Bacopa caroliniana, plus areas throughout Texas, parts of Oklahoma, Arizona and extreme southern California. It has no legal status (is not endangered or threatened) and is not considered invasive, so is OK to collect, transport and keep. Another species, Bacopa rotundifolia, is found in most of the range of the other Bacopa species mentioned (oddly, it is not recorded in South Carolina, Georgia or Florida), and further includes most of the Mississippi valley, the central plains and north to Wisconsin, then west to Idaho, even including Alberta, Canada. There are few states west of the Mississippi River that are not recorded as having Bacopa rotundifolia. As the range of this species extends so far north, it is likely more suited to lower temperatures, although specimens or strains from more southern, coastal regions will likely tolerate higher temps. I have yet to try this species submersed, and although I haven't found any photos of it growing submersed, scientific ID sketches show it as having the same habit of rooting and sprouting from nodes just as its relatives do, so I would assume it adapts similarly. Of course, this is speculation on my part, and I stand to be corrected; I would love to hear from someone who has experience with this native plant. On a darker note, this species is listed as "Endangered" in Indiana, so steer clear of it there.
