Gliricidia Sepium

Description

Gliricidia sepium, commonly known as Gliricidia, Mexican Lilac, or Madre de Cacao, is a fast-growing, semi-deciduous tree native to Central and South America. It is highly valued for its versatility and ecological benefits. The tree features pinnate leaves and produces clusters of fragrant, pea-like, pale pink to lavender flowers with yellow throats during the dry season. These blooms are followed by flat, green seed pods that mature into brown pods containing hard, shiny seeds. Thriving in full sun and adaptable soils, Gliricidia sepium is widely used in agroforestry systems for purposes such as living fences, shade for crops, nitrogen fixation, and erosion control. Its leaves can be used as fodder for livestock, and its wood is ideal for firewood and charcoal due to its dense, high-energy content. Additionally, the tree has insecticidal properties, with its leaves and bark traditionally used to repel pests and treat skin conditions.

Sowing Advice

Scarify seeds then soak in warm water (40–50°C / 104–122°F) for 12–24 hours. Sow the seeds 2–3 cm deep in a well-draining seed-starting mix, and lightly cover. Maintain consistent moisture by watering gently, ensuring the soil is not waterlogged. Place the seed trays or pots in a warm, sunny location or greenhouse, maintaining a temperature of 20–30°C (68–86°F) for optimal germination. Once seedlings have two true leaves and are 10–15 cm (4–6 inches) tall, transplant them into individual pots. With proper care, these seeds germinate quickly, and the resulting trees establish rapidly, offering a versatile and sustainable solution for various uses.
