Temple Plant

Hygrophila corymbosa

herb

A tropical aquatic plant native to Asia, commonly used in freshwater aquariums and paludariums. Hygrophila corymbosa is valued for its rapid growth, attractive foliage, and ability to thrive both submerged and in semi-aquatic conditions. It serves as an excellent oxygenator and provides shelter for aquatic fauna.

Growing Conditions

☀️
Sun: Moderate to high light; 8-12 hours daily under full-spectrum LED or fluorescent aquarium lighting
💧
Water: Fully aquatic or semi-aquatic; prefers water temperature 72-82°F (22-28°C), soft to moderately hard water; tolerates a wide pH range; ensure regular water changes (25-50% weekly) to maintain water quality
📏
Spacing: 6-12 inches apart (allow room for lateral growth and canopy development) inches
📅
Days to maturity: 30-60 days to reach usable size; continuous growth thereafter
🌱
Planting depth: Plant stem cuttings 1-2 inches into substrate; bury lower leaves slightly for rooting

Soil

Type: Nutrient-rich aquarium substrate or specialized aquatic plant soil
pH: 6.0-7.5
Amendments:
Aquarium plant fertilizer (all-in-one or macronutrient focused) Micronutrient supplements (iron, trace elements) CO2 injection (optional but beneficial for optimal growth) Root tabs for substrate-rooted nutrient uptake

Growth Stages

1

Establishment

1-2 weeks

Newly planted stems develop roots and adjust to aquatic conditions; leaves may show mild melting or discoloration

Maintain stable water parameters, ensure adequate light, and provide gentle water circulation; patience is key as adaptation occurs

2

Vegetative Growth

4-8 weeks

Stems elongate rapidly, producing new leaf pairs at regular intervals; plant develops a robust root system

Fertilize regularly (liquid or root-based nutrients), maintain 8+ hours of quality lighting, perform weekly water changes, and consider CO2 supplementation for accelerated growth

3

Lateral Branching

3-6 weeks

Plant develops side shoots and a fuller, bushier form; canopy becomes denser and more aesthetically prominent

Prune upper stems to encourage lateral branching and remove any yellowing lower leaves; maintain consistent nutrient and light levels

4

Maturation & Maintenance

Ongoing

Plant reaches full size and form; growth continues but at a slower rate; may produce flowers in emergent conditions

Continue regular fertilization, perform periodic pruning and re-planting of cuttings, and monitor for nutrient deficiencies; remove decaying leaves promptly

5

Propagation

1-2 weeks for rooting

Stem cuttings develop roots when separated and replanted; plant readily regenerates from cut portions

Take 3-4 inch cuttings from healthy stems, remove lower leaves, and plant immediately in substrate; rooting occurs within 1-2 weeks

Companion Planting

Plan your garden →

Plant with:

Avoid planting near:

Large, aggressive stem plants that compete heavily for light and nutrients Rooting plants that may be outcompeted in confined aquascapes

Common Pests

  • Maintain balanced nutrient levels, reduce light duration if excessive algae develops, increase plant biomass to outcompete algae, perform water changes, use algae-eating fauna (Otocinclus, Amano shrimp)

  • Dose all-in-one or targeted fertilizers weekly; iron deficiency shows as yellowing new leaves (treat with chelated iron); nitrogen deficiency causes stunted growth (increase macronutrient fertilizer)

  • Common during acclimation; improve water quality, ensure adequate lighting, trim decaying portions, maintain stable temperature, and be patient

  • Verify light duration (8+ hours), test water parameters, increase fertilization frequency, ensure adequate water circulation, and consider CO2 supplementation

Uses

🏠

Aquarium Oxygenation & Aesthetics

Household

Hygrophila corymbosa is a prolific oxygen producer via photosynthesis, improving water quality and creating a visually appealing planted aquascape. Its rapid growth and attractive leaf structure make it a cornerstone plant for freshwater aquariums and paludariums. [source]

🦋

Fish & Aquatic Fauna Habitat

Wildlife

Provides shelter, shade, and spawning sites for fish and invertebrates; dense foliage supports beneficial microbial biofilm growth and offers grazing surfaces for algae-eating organisms. Creates a natural microhabitat within the aquatic ecosystem. [source]

💊

Traditional Asian Medicine

Medicinal

Hygrophila corymbosa is used in Ayurvedic and traditional Asian medicine systems to treat inflammation, improve digestion, and support respiratory health. The plant contains bioactive compounds with potential anti-inflammatory and antioxidant properties. [source]

🍳

Culinary Vegetable in Asian Cuisine

Culinary

In Southeast Asia, young leaves and stems are harvested and consumed as a nutritious leafy vegetable, often stir-fried or added to soups. The plant is prized for its tender texture and mild, slightly bitter flavor profile. [source]

🏠

Water Filtration & Nutrient Absorption

Household

Acts as a living biofilter by absorbing excess nutrients (nitrogen, phosphorus, potassium) from aquarium water, reducing algae blooms and maintaining stable water chemistry. Particularly effective in tanks with moderate bioloads. [source]

Harvest Tips

Not a harvest plant in the traditional sense; instead, propagate by taking 3-4 inch stem cuttings with 2-3 leaf pairs, removing lower leaves, and replanting in substrate. Cuttings root within 1-2 weeks. Trim regularly to maintain shape, encourage bushier growth, and prevent the plant from shading lower portions of the aquascape. Remove yellowing or decaying leaves promptly to maintain plant health.

Fun Facts

  • 🌱 Hygrophila corymbosa can grow submersed (underwater), emersed (above water with roots in substrate), or paludarial (partially submerged); leaf morphology changes depending on the growth form, with submerged leaves typically narrower and emersed leaves broader.
  • 🌱 The plant is sometimes called 'Hygro' by aquarists due to its rapid growth rate and hardiness; it is one of the most beginner-friendly stem plants and can grow several inches per week under optimal conditions.
  • 🌱 In its native Asian habitat, Hygrophila corymbosa inhabits wetlands, marshes, and slow-moving streams; it is highly adaptable and has naturalized in warm regions worldwide, making it one of the most widely cultivated aquatic plants globally.
