Ludwigia Super Red Mini

Ludwigia sp. 'Super Red Mini'

plantfreshwater

Ludwigia Super Red Mini is a highly popular aquascape stem plant producing small, rounded leaves of an intense, uniform blood-red colour that few other plants can match. The compact leaf size and bushy growth habit make it more versatile than larger ludwigia species — it works equally well in nano tanks and as a detailed midground splash of colour in larger aquascapes. Adequate iron and CO2 are key to maintaining colour intensity.

Marsilea Crenata

Marsilea crenata

plantfreshwater

The most popular carpeting Marsilea in the hobby, producing tiny two- or four-leaf clovers on short petioles that hug the substrate to form a dense, bright green carpet. Significantly smaller than M. hirsuta, making it better suited to nano tanks and foreground work in larger scapes. Grows reliably with good light and CO₂ but is surprisingly tolerant of lower-tech conditions compared to HC Cuba. The clover-shaped leaves are charming and create an instantly recognisable, naturalistic foreground.

plant

Marsilea Hirsuta

Marsilea hirsuta

plantfreshwater

Marsilea Hirsuta is a low-maintenance carpet plant that produces small, clover-like leaves on short stems. It spreads via runners to form a lush, medium-height green carpet without requiring CO2 injection — making it one of the easiest carpet plants for low-tech tanks. Leaves grow taller without CO2 but stay compact with it.

plant

Marsilea Minuta

Marsilea minuta

plantfreshwater

The smallest Marsilea species commonly available, producing miniscule two-leaf forms when submerged that create an incredibly fine, lawn-like carpet. Its wide geographic distribution makes it very adaptable to different water conditions. Under high light it carpets tightly to the substrate; in lower light, petioles elongate as the plant reaches for the surface. One of the most low-maintenance carpeting options available — more forgiving than HC Cuba or E. Belem.

Marsilea Quadrifolia

Marsilea quadrifolia

plantfreshwater

The four-leaf clover aquatic fern produces charming four-lobed leaves that resemble tiny clover on short stalks. It can be grown as a compact foreground carpet in high-light CO2 tanks, or left to grow taller as a decorative mid-ground plant in low-tech setups. A unique texture plant that adds whimsy to any scape.
