Pilea microphylla

Pilea microphylla, commonly known as the artillery plant, is a low-growing, mat-forming herbaceous species in the nettle family (Urticaceae). It features delicate, fleshy, light green stems and tiny, asymmetrical leaves arranged in opposite pairs. The leaves are obovate, narrowing to a point, and measure up to 9 mm in length. Notably, the plant produces minute greenish flowers that release pollen explosively—a trait that inspired its common name.

This plant is often cultivated indoors in terrariums for its compact growth habit and ease of care. It is suitable for both small pots or terrariums and can be propagated easily through stem cuttings or division. 

Native to:
Pilea microphylla is native to tropical and subtropical regions of the Americas, including southern Mexico, Central America, the Caribbean, and northern South America. It typically grows in moist, shaded habitats such as rocky outcrops, old masonry walls, and disturbed urban areas. 

Water:
Maintain moderately moist soil, allowing the top third of the potting mix to dry out between waterings. Overwatering can lead to root rot, while prolonged dryness may cause leaf drop. During the growing season, water more frequently, reducing the frequency in cooler months.

Light:
Provide bright, indirect light. Direct sunlight can scorch the leaves, leading to browning and leaf drop. A position near a north or east-facing window is ideal. If natural light is insufficient, consider using artificial grow lights.

Humidity:
Thrives in moderate to high humidity levels (around 60% or higher). Regular misting, placement on a humidity tray, or use of a humidifier can help maintain adequate moisture in the air. Its compact size and humidity preference make it suitable for terrarium cultivation.

Temperature:
Prefers warm temperatures ranging from 18°C to 24°C. Avoid exposure to temperatures below 15°C, as cold drafts can damage the plant. Keep it away from heating vents or air conditioners to prevent sudden temperature fluctuations.
