Safety Overview
1.Lemon Thyme — Introduction & Highlights
Lemon Thyme, scientifically known as Thymus citriodorus, is a charming perennial herbaceous subshrub belonging to the Lamiaceae family, which also includes common thyme (Thymus vulgaris) and oregano. This low-growing plant typically forms a mounding carpet, reaching a modest height of 15 to 30 cm and spreading up to 30 cm wide. Its small, ovate leaves, usually 1 to 2 cm long, present a vibrant green hue, often adorned with subtle yellow or golden variegation, depending on the cultivar.
When bruised or brushed, the foliage releases a distinctly refreshing, potent lemon aroma, a hallmark of its rich essential oil content. During the summer months, Lemon Thyme produces delicate tubular flowers, ranging in color from soft pink to pale purple, which serve as an attractive beacon for various pollinators, particularly bees. The plant's base features woody stems, contributing to its robust, bushy appearance, while younger growth may exhibit a slightly hairy texture.
Originally thought to be a hybrid, DNA testing has since confirmed Thymus citriodorus as a distinct species native to Europe and the Mediterranean region. It thrives in sunny, dry conditions and prefers well-drained, sandy or rocky soils, making it a resilient and adaptable addition to diverse garden landscapes.
