Salvinia oblongifolia

Description

The largest of all Salvinia species, rare, but not demanding in cultivation. The fern grows as a floating rhizome with three leaves per node. Two of the leaves are developed as floating leaves heavily hairy on the upper side, the third leaf is split into fine threads and hangs downwards. It is called a "water leaf" and thus takes on the role of roots, which the fern lacks.

The floating leaves grow up to 8 cm long and 3 cm wide, the water leaf grows about 15 cm long.

Salvinia oblongifolia originates from eastern Brazil and grows there in still or slow-flowing, nutrient-rich, warm, and sun-drenched waters. The lotus effect of the floating leaves is particularly impressive in this large species.

In the aquarium, it grows very quickly under good conditions and provides an ideal habitat for young fish with its water leaves.

You will receive a portion approximately 10 cm long.
Care tips

Salvinia are free-floating ferns that form their own family. They typically grow on nutrient-rich (eutrophic), warm stillwaters or slow-flowing rivers.

They can be successfully cultivated in open aquariums or bowls. In closed aquariums, they tend to grow poorly and rot due to the stagnant, humid air.
Light & Location

This Salvinia requires a lot of light and should be cultivated either under strong grow lights or with direct sunlight, e.g., behind a south-facing window. It grows well at 5000 to 12000 Lux or 110 to 250 PPFD (µmol/m²/s), and the leaves reach their impressive final size.

It should always have water above 20°C; temperatures up to 28°C are also well tolerated. Water movement should not be too strong. The floating leaves should always remain dry and not be misted. This floating fern does not tolerate stagnant air well, such as under an aquarium cover.
Substrate & Repotting

It has no special requirements regarding water parameters. However, water that is too soft and nutrient-poor leads to stunted growth. It grows well in regular tap water and also tolerates many nutrients well.

Watering & Fertilizing

In an aquarium with a large fish population, additional fertilization is not necessary. When cultivating in a bowl or an aquarium without fish, you can fertilize weekly with approx. 500 µS/cm. A normal houseplant fertilizer can be used for this.

For even better leaf coloration, especially if the plants receive a lot of light, regular fertilization with an iron fertilizerwill help.
