Safety Overview
1.Lavender — Plant Snapshot
Lavender, scientifically known as Lavandula angustifolia, is a cherished herbaceous perennial shrub belonging to the esteemed Lamiaceae family, commonly recognized as the mint family. This aromatic plant typically grows to a height of 60-90 cm, presenting a compact, bushy form. Its foliage consists of narrow, linear, silver-green leaves that are evergreen, releasing a distinctive fragrance when brushed or crushed. The most striking feature of Lavandula angustifolia is its inflorescence, composed of slender, erect spikes adorned with numerous small, intensely fragrant, purple-blue flowers. These delicate blossoms are arranged in whorls along the stem, creating a visually appealing and highly aromatic display.
Native to the mountainous regions of the Mediterranean, particularly southern France, Italy, and Spain, Lavandula angustifolia thrives in full sun and prefers poor to moderately fertile, well-drained, alkaline soils. Its natural habitat includes dry, rocky slopes and garrigue, demonstrating its remarkable drought tolerance once established. Historically, its geographic distribution has expanded significantly due to widespread cultivation for its essential oil and ornamental value across temperate climates worldwide, including parts of North Africa, the Middle East, Southwest Asia, and even Southeast India. Taxonomically, Lavandula angustifolia is also known by its synonyms Lavandula vera and Lavandula officinalis, reflecting its long-standing recognition and medicinal applications. Its historical significance dates back thousands of years, with ancient civilizations revering its multifaceted properties.
The name 'Lavender' is believed to derive from the Latin word 'lavare,' meaning 'to wash,' a testament to its ancient use in baths for purification and hygiene by the Romans. The Egyptians incorporated lavender oil into their mummification processes and cosmetics, while the Greeks utilized it for various ailments, including headaches and indigestion. Throughout medieval Europe, lavender was a common strewing herb, prized for its ability to mask odors and deter pests. Its enduring legacy as a symbol of purity, tranquility, and healing continues to this day, making it one of the most extensively researched and utilized medicinal plants globally.

10.Lavender — Propagation & Care
- ✓Site Selection — Choose a location with full sun exposure, receiving at least 6-8 hours of direct sunlight daily for optimal growth and essential oil production.
- ✓Soil Requirements — Lavender thrives in poor to moderately fertile, well-drained, slightly alkaline soil (pH 6.5-7.5). Avoid heavy, clay soils that retain too much moisture.
- ✓Drainage Enhancement — If soil drainage is poor, amend with sand, gravel, or organic matter like compost to improve permeability. Raised beds are also an excellent option.
- ✓Watering Regimen — Once established, Lavandula angustifolia is highly drought-tolerant. Water sparingly, only when the top few inches of soil are dry, especially during prolonged dry spells.
- ✓Propagation — Primarily propagated from semi-hardwood cuttings taken in late spring or early summer. Seeds can be used but may result in variable plant characteristics.
- ✓Spacing — Plant individual lavender plants 2-3 feet apart to ensure adequate air circulation and prevent fungal diseases, allowing for mature size.
- ✓Pruning — Prune annually after the main flowering flush (typically late summer) to maintain shape, encourage bushiness, and prevent woody growth. Remove about one-third of the plant's growth.
- ✓Fertilization — Lavender generally does not require heavy fertilization. An annual application of a balanced, slow-release fertilizer or compost in spring is sufficient if soil is very poor.
- ✓Pest and Disease Management — Lavender is generally resistant to most pests and diseases. Ensure good air circulation to prevent fungal issues like root rot in humid conditions.
- ✓Winter Hardiness — Lavandula angustifolia is hardy to USDA Zone 5, tolerating cold temperatures. In colder zones, provide winter protection or grow in containers that can be moved indoors.
- ✓Harvesting — Harvest flowers when about half of the flower buds have opened, typically in late spring to early summer, for the highest concentration of essential oils. Cut stems just above the leaves.
