Alternanthera Bettzickiana 'Red' (Red Joyweed or Calico Plant)
Alternanthera bettzickiana 'Red' (also known as Red Joyweed or Calico Plant) is a popular, vibrant perennial herb famous for its striking pink-to-red stems and variegated foliage. It is widely used by hobbyists in aquariums, terrariums, and high-humidity vivariums because it adapts well to both submerged and emersed growth.
Growth Environments
Aquarium Care (Submerged)Coloration: Leaves display deep green, glossy textures with light pink or red highlights. Under intense lighting, the leaves turn a rich, deep red.
Nutrients: Benefits greatly from root fertilizers and liquid iron supplements.
Trimming: Regular pruning helps maintain a bushy, compact shape.
Acclimation Note: When purchased in its emersed (out-of-water) form, old leaves may melt away as new underwater growth takes over.
Terrarium & Paludarium Care (Emersed)
Humidity: Thrives in high-humidity setups.
Soil: Prefers nutrient-rich, moist substrate or fine gravel.
Versatility: Exceptionally hardy and easy to grow when kept damp out of water.
Propagation & Safety
Propagation: Very easy to propagate. Cut the upper stems and replant them back into the substrate. New roots form quickly.
Fauna Safety: Completely shrimp-safe, snail-free, and pest-free when bought from clean, tissue-cultured, or quarantined lines.
