Alternanthera reineckii – Colorful Red-Purple Stem Plant for Freshwater Aquariums

Alternanthera reineckii is one of the most popular stem plants for aquascaping, prized for its vivid red to purple leaves that bring dramatic color contrast to freshwater aquariums. Originating from South America, this species grows upright with long, lance-shaped leaves arranged in pairs, forming a dense and vibrant cluster when planted in groups. Its bold hues make it a perfect focal point for Dutch-style and nature aquascapes.
