Throughout the time there have been numerous researches on the particularities of growth, flowering, hybridization, fertilization of species, varieties and cultivars of Hosta. The present article presents a brief summary of some research conducted in recent years on Hosta. The purpose of these studies is to evaluate the behavior of Hosta as perennial plants, to identify the different colours of the flowers due to the presence of anthocyanins in the tepals, the presence of volatile oils in flowers, the presence of macro and micro minerals in the leaves, to investigate the possibility of storing the seeds of Hosta, to establish the flowering period, the nectar production and flower pollination. The current review addresses the following issues: Growth, flowering and leaf character variation of Hosta; Anthocyanins of the genus of Hosta and their impacts on tepal colors; Analysis of the variation in scent components of Hosta flower by HS-SPME and GC-MS; Nectar and polen production and insect visitation on ornamentals from the genus Hosta Tratt. (Asparagaceae); Analysis of essential macro-micro mineral content of twelve Hosta taxa. Seed storage longevity of Hosta sieboldiana (Asparagaceae).
