About Long-feathered Aponogeton

Aponogeton longiplumulosus · also called Long-feathered Aponogeton, Ruffled Aponogeton · houseplant

A stunning Madagascar species with extraordinarily long, finely and densely ruffled leaves that ripple with the slightest current. Its flowing foliage of 35–60 cm creates dramatic movement in the aquarium background. It requires moderate-to-bright lighting and a nutrient-rich root zone, and rewards patient keepers with periodic fragrant flower spikes reaching the water surface.

Preferred mix: Fine gravel or aquarium soil enriched with root fertilizer tablets

Watch for — Weak, narrow ruffling: Characteristic dense, dramatic ruffling only develops under adequate lighting and good root nutrition. Leaves in low-light or nutrient-poor setups are thin, elongated, and poorly ruffled. Increase light intensity and ensure root tabs are replaced regularly.
