About Guinea henweed
Petiveria alliacea, commonly known as Guinea Henweed or Anamú, is a perennial herbaceous plant native to the tropical regions of the Americas. Its leaves emit a distinct garlic-like aroma when crushed, and it produces small, whitish flowers on slender spikes. It is ideal for herb gardens or as an ornamental plant in warm climates, though its primary use is medicinal and culinary in various cultures.
Native range
Tropical South and Central America
Care tips
It prefers full sun to partial shade and a warm, humid climate, free from frost. Watering should be regular, keeping the substrate consistently moist but well-drained; it tolerates short periods of drought once established. Use a substrate rich in organic matter and with good drainage. A common mistake is planting it in waterlogged soils, which can lead to root rot.
