Plant Needs
Sunlight
Full sun to partial shade; requires at least 6 hours of direct sunlight daily for optimal tuber development
Watering
Keep soil consistently moist but not waterlogged; avoid drought stress during active tuber formation
Temperature
Optimal growth at 15–20°C; temperatures above 25°C inhibit tuber production
Characteristics
- Leaf: Compound pinnate leaves with 7–15 oval leaflets, medium green, slightly hairy
- Flower: Star-shaped, 2–3 cm wide, white to pale purple with yellow central stamens
- Stem: Erect, branching green stems; underground stolons develop into edible tubers
Care Guide
Watering
Maintain even soil moisture during tuber growth; mulch to reduce water loss
Fertilization
Apply balanced granular fertilizer at planting; side-dress with nitrogen when plants reach 15 cm tall. Do not fertilize after early summer to prevent excessive foliage growth
Banana peel compost tea：Use fully composted banana peels; dilute 1:20 with water for root drenching to boost tuber yield and plant healthPruning
- Remove yellowing lower leaves to improve airflow and reduce fungal disease risk
- Pinch off flower buds to redirect plant energy to tuber production if growing for edible harvest
- Cut back dead foliage after harvest to prepare tubers for curing and storage
Toxicity
Warning: this plant may be toxic.
Pets & Humans
Pets: ASPCA: Green plant parts are toxic; mature tubers are non-toxic; ingestion of green material may cause vomiting or diarrhea
Humans: Mature tubers are safe; green foliage, stems, and green tubers contain solanine, causing mild gastrointestinal irritation if ingested in large amounts
Garden Uses & Culture
Culture: Symbolizes sustenance and agricultural heritage in global food systems
Usage: Primary staple food crop; ornamental foliage in decorative garden beds
