The Floriculture Department of the Botanical Garden Vilnius University was established in 1992. Herbaceous ornamental (field flower) collections rich in genera, species, cultivars, and hybrids (3200 plant names of 80 families and 324 genera) have been accumulated and preserved. In 2002 in the Botanical Garden (in Kairėnai) of Vilnius University have been accumulating, preserving and investigating the of herbaseous ornamental plants Dahlia cultorum Thorsrud et Reisaeter, Hemerocallis L., Iris

The genefund consists of 886 flower taxa developed by Lithuanian breeders. The morphological-ornamental and bio-ecological properties of the genera Dahlia cultorum Thorsrud et Reisaeter, Iris L., Primula L. and Tulipa L. were investigated and estimated. 20 Dahlia cultorum Thorsrud et Reisaeter, 5 Iris L., 10 Primula L. and 20 Tulipa L. cultivars released by Lithuanian breeders are recommended to be included into highest priority list of Lithuanian genetic resources conservation. Recently the garden is involved in the programmes of the plant genefund research and protection, other scientific and other education projects. MATERIALS AND METHODS The investigations, descriptions and evaluations of morphological, phonological, propagation and ornamental properties of Dahlia cultorum Thorsrud et Reisaeter, Iris L., Primula L. and Tulipa L. cultivars were carried out in the period of 1998-2003 according to the requirements of the International Union for the Protection of New Varieties of Plants (UPOV) and methodologies used in neighbouring
