Bacopa is a perennial aquatic herbaceous plant widespread in most tropical and subtropical regions of Asia, America, Australia and Africa. It has thin fleshy stems, very branched, creeping, erect; which grow mainly under water, and carry numerous small, succulent, thick, light green leaves; the stems are covered with a thin hair; the stems that reach the surface, rising from the surface of the water, produce numerous flowers with 4-5 petals, white or lilac. These plants tend to spread and become upholstered, they can also be grown in the aquarium, like submerged plants, but in this case they do not produce flowers; It is also possible to grow monnieri species in a container or to place them in a place where they have completely emerged, in this case it is good, however, to remember to water the plant very often.
These species can bear both the sun and the shadow, provided it is luminous; in general it does not fear the cold if the sheet of water in which it is inserted does not freeze. The bacops prefer to be planted completely submerged, or on the banks of ponds or streams with fresh and clear waters, they do not adapt well to the low ponds which are very hot in July-August; to have a greater visual impact it is good to put some nearby plants in order to create a spot of color.
To be able to develop the best the bacopa need to be buried in a well-drained and sandy substratum, very rich in organic substance and minerals, if possible it is recommended to provide fertilizer for aquatic plants every 2-3 weeks, during the vegetative period .
The plant can also be grown in the aquarium. In this case it will be necessary to place at the bottom of our aquarium specific material that allows the roots of the plant to anchor and receive the nutrients it needs, especially ferrous and rich in mineral salts.
The multiplication of the plant takes place by seed, which the plant produces in large quantities in small woody pods; the seeds are placed in the seedbed at the beginning of spring and the new seedlings are cultivated like the other perennials, they are planted when the stems have reached 10-15 cm in length. Plants can also be propagated by cutting, removing the tips of the stems in spring.
It is also possible to buy seedlings of this species in the main nurseries in the area. In the specialized garden centers, however, only the most common species can be found, while the bacopa Madagascarensis and the bacopa Myriophylloides represent two species that are difficult to spread and therefore the search for these two varieties may take some time.
