Plant Needs
Sunlight
Partial to full sun; tolerates light afternoon shade in hot, dry climates to prevent leaf scorch
Watering
Keep soil consistently moist or saturated; thrives in boggy or pond-edge conditions and should not be allowed to dry out completely
Temperature
Hardy to mild frosts (down to 0°C); avoid prolonged temperatures above 30°C which can cause leaf wilting and reduced growth
Characteristics
- Leaf: Lanceolate to oblong leaves with wavy margins, bright green, up to 25 cm long
- Flower: Tiny greenish-red clustered flowers on branching upright spikes
- Stem: Erect, smooth reddish-green stems with faint longitudinal ridges
Care Guide
Watering
Maintain saturated or consistently moist soil; top up standing water levels during dry spells
Fertilization
Diluted balanced liquid feed every 2 weeks. Cease fertilization in late autumn when active growth slows to prevent nutrient buildup in cool, wet soil
Banana peel compost tea：Compost banana peels for 2 weeks, steep in water for 48 hours, dilute 1:20 with water for root drench; avoid applying undiluted mixture to prevent root burn and odorPruning
- Deadhead spent flower spikes to control self-seeding and redirect energy to foliage growth
- Trim yellowing lower leaves to improve airflow and reduce fungal disease risk
- Cut back foliage to 10 cm above soil level in late autumn to encourage dense, healthy spring regrowth
- Remove damaged or diseased stems promptly throughout the growing season
