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.

Ludwigia repens X arcuata

This Ludwigia is a hybrid between the North American species L. repens and L. arcuata. It is long known and has proven as an undemanding, colourful stem plant. Its lanceolate leaves become blood-red under good light. The stems are densely set with leaves; the internodes are short.

Ludwigia repens x arcuata is well adaptable to different water chemistry and has a high growth rate. Nutrient-rich bottom and medium to strong lighting are very beneficial for its growth. It tolerates quite cool water, however its temperature optimum lies between 24 and 28 °C.

As a group in the midground to background, this Ludwigia provides a colourful eyecatcher. Due to its low demands, it is also recommendable for beginners and for the primary planting of new tanks, respectively.
