Lagenandra lancifolia (Schott) Thwaites

• Genus: Lagenandra
• Botanical Background: Described by botanist Heinrich Wilhelm Schott and was later revised by Thwaites. It is part of a genus that historically has had some taxonomic confusion, often being classified under other related genera.

• Geographical Range: Native to Southeast Asia, specifically found in the tropical wetlands and freshwater habitats of Sri Lanka and India.
• Environment: Thrives in humid, waterlogged environments, often found in swamps, slow-moving streams, or the edges of ponds. It prefers moderate sunlight and a consistently moist or submerged environment with nutrient-rich soils.

Leaves

• Long, narrow, and lance-shaped
• Lengths of 30-50 cm
• Glossy and dark green surface
• Exhibit strong venation

Inflorescence (Spadix & Spathe)

• Consists of a typical Aroid spadix and spathe
• Inconspicuous compared to the foliage
• Spathe is usually greenish or creamy, and the spadix is unremarkable in size and scent

Growth Habit

• Plant is aquatic
• Grows in submerged or partially submerged conditions
• Not a climber and grows as a spreader in its natural habitat

Light Requirements

• Bright, indirect light
• Can also adapt to low light conditions

Watering & Humidity

• Consistently wet conditions
• Should be grown in a waterlogged substrate or water garden
• High humidity

Soil & Potting Mix

• A soil mix that retains moisture, such as a rich, organic soil blend with added perlite or coarse sand
• Containers that can hold water

Temperature & Fertilizer

• Temperatures between 18-24°C (65-75°F)
• A mild, balanced liquid fertilizer, applied monthly

Division and Stem Cuttings

• Dividing the rhizomes
• Can also be grown from sections of the rhizome that contain at least one growing bud

Seeds

• Rarely practiced due to the plant's preference for vegetative propagation methods
• If seeds are used, they require warm, moist conditions to germinate

Typical Issues

• Aphids, snails, and mealybugs
• Root rot

Treatment Recommendations

• Insecticidal soap or neem oil
• Ensure the substrate is well-draining and not kept stagnant for too long
• Fungicides

• Aesthetic appeal and unique growth form
• Used as an ornamental plant in tropical water feature

• Elegant, lance-shaped foliage
•  Ability to thrive in aquatic environments

Wild Population Status

• Not listed as endangered
• Natural habitats in wetland areas are under threat due to land development

Market Availability

• Relatively rare in the general plant market
• Can be found in specialized Aroid collections or water garden nurseries
• Commonly grown for commercial sale
