Henna (Lawsonia inermis, also called mignonette tree) is a flowering plant used since antiquity to dye skin, hair, fingernails, leather and wool. The name is also used for dye preparations derived from the plant, and for the art of temporary tattooing based on those dyes. Additionally, the name is misused for other skin and hair dyes, such as black henna or neutral henna, which do not derive from the plant. The English name "henna" comes from the Arabia.
How to Grow Henna
The intense fragrance of henna blooms evoke a romantic, sensuous atmosphere. A favourite hedging plant in ancient times, it is cultivated in private gardens and public spaces all over the world, thriving in areas where the climate is similar to the hot, dry conditions where it evolved. A shrubby tree that will grow to 3-6m (10-20ft) unless it is kept trimmed, it bears long spines and fragrant white flowers.
The seeds will germinate best in hot conditions, and can be pretreated by soaking in water for a week, ensuring water is changed daily. Seeds can then be sown in a lightweight sterilized soil mix, and kept evenly moist but not soggy. Germination should take place within 2 weeks, at which point seedlings can be gradually exposed to bright light. Bottom heat of 25°C (75°F) can help speed germination. If it is not to be planted right away, seed should be refrigerated to preserve its viability.
Henna leaf detail.
The plant prefers hot dry conditions, and cannot be grown where temperatures consistently go below 10°C (60°F). In temperate areas it is grown containers so it may be moved indoors during cool weather. It is the sharp, lanceolate leaves that contain the colouring agent lawsone, and the hotter and drier the growing conditions, the more concentrated the lawsone becomes in the leaves, producing the darkest red-oranges. Harvesting of leaves can begin when the tree is five years old. Henna is a heavy feeder in the garden, and although it is adaptable and tolerates poor soils, it will appreciate a well-prepared bed with good fertilizer. Areas with heavy rainfall are not conducive to growth, making this lovely shrub perfect for the xeriscaper.
