Lavender is a perennial plant in semi-shrub form and has a strong taproot structure that can go to a depth of 80-100 cm, depending on climatic conditions. Thanks to this strong pile root structure, the plant can adapt to many arid regions of the world. As the plant ages, there are many branches that start to lignify from the bottom to the top, and on these branches there are leaves of 2-6 cm long, very short stems, grayish green, arranged opposite each other. Both sides of the leaves of the lavender plant are covered with cottony hairs containing essential oil.
The flowers of the plant are collected at the ends of bare stems 20-30 cm long. The length of the flower spike is 15-20 cm. Each spike has an average of 5-6 flower clusters and each cluster has 5-15 flowers. Lavender flowers with very short stems are surrounded by 5 mm long sepals of gray-blue color, smooth and shiny inside and hairy outside. On the outer edges of the sepals, there are many small, single-celled hairs that store essential oil. The lavender plant is a plant with small seeds, the length of the seed is 2 mm and the width is 1 mm. The shape of the seed is elongated oval and the color is bright dark brown.
