Bacopa caroliniana

Bacopa caroliniana originates from US and has been used as an aquarium plant for many years. Stems become 10-30 cm long and 3-4 cm wide, branching willingly from the bottom. It has few demands and thus very convenient for beginners. Its slow growth rate makes it one of the few stem plants that do not need much attention.
Like most stem plants, it is most decorative when planted in small groups. Easy to propagate by cuttings; take a side shoot and plant it in the bottom.

Heteranthera zosterifolia

Heteranthera zosterifolia from South America is an extremely beautiful plant, which forms a lot of side shoots and thus quickly forms a bushy plant group.

Stems can become 30-50 cm tall and 6-12 cm wide. Leaves often become black on the back. In strong light growth is intensive, and the plant must be pruned before it becomes so compact that no light reaches the lower leaves. Water roots often form on the stem. Those are easily cut and replanted.

In open aquariums, it forms small blue flowers if some shoots are allowed to spread on the surface.
