This is a detailed botanical study of two parts about lavender cotton (Santolina chamaecyparissus L.). In this paper, the morphological characters of plant are investigated. Lavender cotton is an evergreen dwarf subshrub 40 cm high, silvery gray and much branched, often propagates from cuttings of tender new growth at branches terminal. The root system is adventitious. The main stem and plant height increased slowly in length during the whole growing season with a total increase of some 10 cm. The main stem increased in the mean time in both of its length and the number of internodes. The plant developed a great number of lateral branches of different degrees with a maximum of 13.8 primary branches and 77.0 secondary branches. Growth of plant is depending mainly on the lateral branches. Leaves are 1.5-2 cm long, simple, spatulate, pinnately lobed, alternately arranged and petiolate. Leaves are aromatic when crushed. Flowering stage started April- May. Toward mid-August the main stem terminated into an inflorescence of flower buds followed by the lateral branches. Flowering continued throughout a period of four months Plant developed a maximum of 126.3 inflorescences. The inflorescence is a simple racemose head developing solitary at shoot apices of main stem and lateral branches.
