In decorating the interior, besides the potted plants, greenery and flower species are used for the cut. In the floral design there are certain techniques and rules of the arrangement of the plant material. They are subject to demands but also seasonal changes with regard to occasional or permanent availability of flowers and greens. Also, from th every moment of its harvest, it is important to treat the trimmed blades of ornamental plants, to store them and maintain the freshness. The main goal of the research was to determine basic techniques in flower arrangement and installation; which types of greenery and flowers are used in used floral design; the determination of which plant species are constantly present in the application and have seasonal character; the state of the flower market in the area of Zagreb - The Green Market, and which are the methods and procedures for keeping the freshness of plant material (vase life). Basic techniques in flower arrangements and installations were explored based on the literature. The practical part of the research was carried out in the „Flora hall Arkadia“, where during the year floral types and greenery for the cut appeared and were used in floral design. The taxonomic relation and origin of the species were determined, and species with seasonal character and recorded methods and freshness maintenance acts were seperated. In the flower salon "Arkadija", 21 species of the greenery for the cut wewr classified into 18 families. Each of them are represented through two species of the family Ericaceae, Lamiaceae and Myrtaceae, all other family are represented by one species. All species within the family Ericaceae, Lamiaceae and Myrtaceae, except Eucalyptus gunnii Hook. have a seasonal character. From all of the flower species, for the cut were 47 out of 27 families. The largest family is Asteraceae with five species. We have all off these five species in domestic production and import. To maintain freshness, in the flower salon "Arkadija", they primarily satisfy initial conditions such as clean and desinfected vases, keeping flowers that are healthy and not demaged, adding chlorine, vitamin C (absorbic acid), aspirin (acetylsalicylic acid) and sugar (sucrose) to ensure diet or source of energy and prevention of the development of bacteria.
