Stem Plant

Ammannia gracilis is a striking, large stem plant native to West Africa. Known for its deeply colored wavy leaves that range from pale green to intense reddish-pink under optimal conditions, it is a demanding species that requires high light, rich nutrients, and CO2 injection to truly thrive and prevent lower leaf drop.

A classic, beginner-friendly stem plant known for its thick, fleshy leaves that emit a distinct lemon scent when crushed. It grows relatively slowly for a stem plant, making it easy to maintain, and can develop attractive reddish-copper hues under intense lighting.

A fast-growing, bright green stem plant with deeply incised, feathery leaves. Native to South America, it provides excellent textural contrast against broad-leaved or red plants and creates dense, bushy thickets when regularly trimmed.

Mermaid Weed is a striking stem plant famous for its unique leaf morphology. When grown submerged under high light, its leaves transform into deeply serrated, feathery needles that develop stunning copper, orange, or deep pinkish-red hues. Emersed growth is noticeably different, featuring solid, saw-toothed leaves. It typically requires high lighting and CO2 injection to maintain its intricate submerged leaf shape and vibrant colors, making it highly valued as a midground or background accent plant in high-tech aquascapes.

A remarkably fast-growing, undemanding stem plant characterized by its deeply lobed leaves that resemble oak foliage. Due to its vigorous growth, it is an excellent choice for rapidly absorbing excess nutrients, though it requires frequent trimming to prevent it from shading out other plants or taking over the aquascape.

Mint Charlie is an adaptable and distinct stem plant belonging to the mint family. Recognizable by its rounded, bright green opposite leaves and square stems, it often emits a characteristic minty fragrance when trimmed or grown emersed. It thrives both submerged in aquariums and emersed in paludariums, preferring moderate lighting to maintain compact growth.

Bacopa monnieri, commonly known as Moneywort, is an exceptionally hardy and adaptable stem plant characterized by its thick, light-green, rounded leaves. It typically grows vertically in a rigid structure and is well-known for its ability to thrive in a wide variety of water conditions, including low-end brackish environments. It is an excellent choice for beginners due to its undemanding nature.

A popular and highly versatile carpeting plant featuring small, round, bright green leaves. Often chosen as an easier alternative to Dwarf Baby Tears (HC Cuba), it readily creeps along the substrate to form a dense foreground carpet. It can also be attached to hardscape, where it will cascade downwards over rocks and wood.

A highly unique and beautiful stem plant best known for its striking diamond-shaped leaves that form geometric, mosaic-like rosettes on the water surface. Though rooted in the substrate, it sends long, brittle stems upward to display its vibrant red and green foliage at the top of the tank. It requires intense lighting, a nutrient-rich substrate, and still surface water to thrive indoors, making it a delicate but highly rewarding centerpiece for advanced aquarists.

A graceful, fine-leaved stem plant that develops striking orange to deep red coloration under intense lighting and CO2 injection. Frequent trimming encourages dense, bushy growth, making it an excellent midground or background accent in aquascapes.

Pogostemon stellatus 'Octopus' is a highly popular, fast-growing stem plant known for its long, wavy leaves that playfully resemble the tentacles of an octopus. Unlike the notoriously demanding standard form of the species, the 'Octopus' trade profile is incredibly hardy and thrives in a wide range of aquarium conditions. It grows rapidly, providing excellent dense cover for fry and shrimp, and gracefully trails across the water surface if left untrimmed. Frequent pruning is typically required to keep its aggressive growth in check and prevent it from shading out smaller plants.

Parrot's Feather is a fast-growing, adaptable stem plant known for its bright green, delicately feathered foliage. It can grow entirely submerged but is especially famous for breaking the water surface to form thick, robust emersed shoots. Its rapid growth makes it an excellent nutrient sponge, though it requires frequent trimming to prevent it from shading out slower-growing tank mates.

A highly versatile and fast-growing stem plant that can be used as a foreground carpet, midground bush, or background plant depending on how it is trimmed. With its bright green, delicate leaves, it forms dense thickets that provide excellent hiding places for fry and shrimp.

A highly unique and versatile stem plant from India known for its deeply lobed, fern-like leaves and strong ability to attach to hardscape. While it can be planted in the substrate where it grows upright, it is most prized for its creeping, epiphytic growth habit when attached to wood or rock. Under high light and good nutrition, the foliage develops stunning burgundy to deep red hues.

Bacopa salzmannii, commonly known in the hobby as Purple Bacopa or Bacopa sp. Colorata, is a striking stem plant that develops intense purple to deep red coloration under high light and CO2 injection. While its growth pattern is similar to the classic Bacopa caroliniana, its unique coloration and slightly more demanding care requirements make it a highly sought-after midground or background accent plant.

Ammannia pedicellata, historically traded as Nesaea pedicellata, is a striking and robust stem plant known for its thick, vibrantly colored stems and contrasting foliage. It can be somewhat demanding, requiring high light and ample nutrients to prevent the lower leaves from blackening or shedding.

Myriophyllum tuberculatum is a stunning, finely-leaved stem plant known for its intense red to rust-colored foliage. It is one of the more demanding Myriophyllum species, requiring high light, consistent CO2 injection, and comprehensive water column fertilization (especially iron and micronutrients) to maintain its vibrant coloration and prevent lower leaves from melting or dropping. When grown in optimal conditions, its dense, feathery whorls make it a spectacular focal point in the midground or background.

A striking stem plant renowned for its serrated leaves that display vibrant green, purple, and red hues under intense lighting. When grown emersed, its leaves emit a distinct, strong herbal fragrance and are commonly used in Southeast Asian cuisine. In the aquarium, it forms dense, colorful thickets but requires good nutrient availability and CO2 injection to maintain optimal coloration and prevent lower-leaf loss.

Staurogyne repens is a versatile, creeping stem plant highly prized for creating dense, bushy foregrounds and carpets. Originating from the Rio Cristalino in Brazil, it develops a surprisingly robust root system for a stem plant. With adequate light and regular trimming, it stays low to the substrate, making it an excellent transition plant between the foreground and midground.

Alternanthera reineckii is a prominent red stem plant that provides a striking color contrast in the aquascape. While it can survive in moderate conditions with greener foliage, it requires high light, CO2 injection, and a strong nutrient supply to exhibit its deepest magenta and red colorations and to prevent lower leaf loss.

Gymnocoronis spilanthoides is an extremely fast-growing, adaptable stem plant known for its distinctive spade-shaped leaves. Often considered a weed in its native and introduced habitats, it makes an excellent background plant for aquariums due to its rapid nutrient uptake, though it requires frequent trimming to prevent it from shading out other plants or breaching the surface.

A fast-growing stem plant known for its distinct star-like leaf whorls. Under optimal conditions with strong light and CO2, it forms very dense bushes that require frequent trimming. It is particularly sensitive to macronutrient deficiencies, which often manifest as black or melting lower leaves.

Hygrophila corymbosa is a robust, fast-growing stem plant known for its large, broad leaves and thick stems. It is an excellent background plant that easily reaches the water surface. It is prone to potassium deficiency, which manifests as pinholes in older leaves. While it can adapt to lower light, moderate lighting prevents it from losing its lower leaves and maintains dense growth.

Tonina fluviatilis is an exotic and demanding stem plant native to the soft blackwater rivers of Central and South America. Known for its unique, umbrella-like bright green foliage, it requires strictly soft water, an acidic pH, high lighting, and CO2 injection to thrive. Due to its sensitivity to fluctuating parameters and requirement for specialized water conditions, it is best suited for advanced aquarists.
