Morphological and Phenological Characteristics of Ornamental Lianas (on the Example of Samarkand City)

Abstract

Lianas are distributed as ornamental, perennial plants that are widely used in landscaping and popular all over the world. However, in recent times, ornamental lianas have also been used for vertical landscaping in residential buildings. Today, many lianas occupy a leading position among plants, due to their landscape features, such as the colorfulness of flowers, the variety of leaf shapes, and their aroma. The practice of growing flowers in Uzbekistan dates back to ancient times. Floriculture came to our republic through the Great Silk Road from China, Egypt, and India. Because of this, ornamental plants have been widely used for landscaping in cities such as Samarkand, Bukhara, Khiva, Shahrisabz, Kokand, and Margilan. Nowadays, perennial lianas are planted on the grounds of the Botanical Garden at Samarkand State University, and collections of these plants have been created. The garden area contains various species of lianas, including Lonicera japonica Thunb, Clematis florida Thunb , P arthenocissus quinquefolia (L.) Planch, Parthenocissus inserta (A.Kern) Fritsch, Hedera spiral L, Hedera canariensis Willd, Campsis radicans L, Wisteria sinensis (Sims) DC, Actinidia chinensis var. deliciosa (A.Chev.), Humulus lupulus L, Aristolochia clematitis L, and several varieties of Rosa canina L. such as Golden Celebration, Paprika, Aspirin, Burgund, and Rosarium Uetersen.
