Cryptocoryne cordata

Cryptocoryne cordata with broad green-bronze leaves - midground aquarium plant

Cryptocoryne cordata is a robust Cryptocoryne aquarium plant native to Southeast Asia, known for its broad, heart-shaped leaves that vary from deep green to bronze or reddish tones depending on lighting and growing conditions.

Growing to a moderate height of 10-25 cm, it is ideal for midground placement where its lush foliage creates a natural, dense backdrop. The leaves have a slightly hammered or bullate texture, adding visual interest and depth to any aquascape.

Cryptocoryne cordata thrives in low to medium lighting and does not require CO₂ injection, though CO₂ will enhance growth and leaf coloration. It benefits from a nutrient-rich substrate, as it is a strong root feeder, and stable water conditions to avoid Crypt melt during adaptation.

Does Cryptocoryne cordata var. cordata need CO₂?
CO₂ is not required but enhances growth and brings out deeper leaf colours.

Why do the leaves melt after planting?
Cryptocoryne species often melt when adapting to new water conditions but regrow once established.

Is Cryptocoryne cordata var. cordata suitable for low-tech tanks?
Yes - it thrives in low to medium light setups without CO₂, making it ideal for beginners.
