Alternanthera reineckii (Emergent Form)

Alternanthera reineckii is a familiar aquarium stem plant celebrated for its vivid magenta, pink, and red foliage under aquarium lighting. In its emergent form, grown with stems rising above the waterline, it produces broader, more intensely pigmented leaves and takes on a more shrubby, upright habit — the colours often deepening even further than the submerged form. This makes it a spectacular bridging plant in the transition zone of paludariums, where the waterline meets the land section.

The emergent form is vigorous and fast-growing, benefiting from regular pruning to maintain a compact, bushy shape. Cut stems can be replanted in the aquatic section to produce new submerged growth, giving this versatile plant a dual role in any paludarium setup. It requires bright light to maintain its vivid pigmentation in both growth forms.
