Alternanthera varieties are long-stalked stem plants that are found in a variety of colors ranging from bright green to dark violet. They can be found with a variety of leaf shapes and overall plant sizes with dwarf versions generally being labelled 'Mini'. They commonly prefer medium light and CO2 levels, however more vibrant colors and rapid growth will result from increases to these parameters. As stem plants, they should be planted directly into the substrate where they will form large, prolifically growing root systems. Naturally, alternanthera varieties are found in well-flooded, marsh-like habitats where they often experience emersed periods. When grown submersed, it is important to regularly trim stems to promote outward growth and keep plants from growing beyond the surface of the water. When alternanthera grow above the surface of the water, they will begin to sacrifice leaves under the water to allocate more energy to the emersed part of the plant. However, these plants will thrive both submerged in an aquarium or emersed in a terrarium.
Alternanthera reineckii 'Rosanervig':
- Has relatively compact growth compared to other alternanthera varieties, making it an ideal mid- to foreground plant depending on the level of pruning
- Sports vibrant pink leaves with lighter colored veins
- Will exhibit more vibrant coloration and rapid growth with increased light and CO2 injection
- Is also referred to as alternanthera cardinalis variegata
