Anubias hastifolia Engl.

• Genus: Anubias 
• Botanical Background: First described by the noted botanist Adolf Engler, this species has contributed to the growing interest in aquatic aroids and has been a subject of study in tropical botany for over a century.

• Geographical Range: Indigenous to West Africa, inhabits slow-moving streams and shaded riverbanks in tropical rainforest regions.
• Environment: Warm, humid conditions with soft, nutrient-rich substrates; favors shaded environments with consistent moisture and minimal direct sunlight.

Leaves

• Hastate, or arrow-shaped, leaves that are medium-sized with a firm, somewhat leathery texture
• Subtle green coloration that may vary slightly depending on environmental conditions

Inflorescence (Spadix & Spathe)

• Modest, with a small, greenish spathe and a compact spadix
• Scent is generally negligible
• Pollination is likely facilitated by small insects in its natural habitat

Growth Habit

• Aquatic herb with a creeping rhizome
• As semi-aquatic, often seen anchored to rocks or driftwood in its native streams

Light Requirements

• Bright, indirect light 
• Tolerates low light exceptionally well, ideal for shaded aquariums and planted water features

Watering & Humidity

• Consistent moisture without waterlogging the rhizome
• Moderate watering with high humidity in terrestrial setups

Soil & Potting Mix

• A  loose, well-draining aquatic substrate enriched with organic matter
• Container that allows for proper drainage and space for rhizome expansion when potted

Temperature & Fertilizer

• Thrives between 72–82°F (22–28°C)
• Balanced water-soluble fertilizer applied monthly during the growing season

Division and Cuttings

• Rhizome division, ensuring each division contains a healthy portion of the rhizome with attached leaves

Seeds

• Uncommon due to low germination rates and the lengthy process required, so vegetative propagation is generally favored

Typical Issues

• Watch for signs of snail damage, algae buildup, or root rot

Treatment Recommendations

• Manual removal combined with safe, fish-friendly treatments for pests
• Maintaining optimal water conditions and routine cleaning

• Plays a role in natural filtration systems within aquariums
• Supports local biodiversity in its native habitat

• Unusual leaf shape and versatility in low-light and aquatic setups
• Robust nature makes an excellent choice for both beginners and seasoned aquascapers

Wild Population Status

• While not currently listed as endangered, habitat degradation in some West African regions may pose future risks

Market Availability

• Generally available through specialty aquatic plant retailers and online collectors
• Unique features may make some cultivars rarer than others
