SEED PROPAGATION OF DIANTHUS GIGANTEUS D´URV SSP. CROATICUS (BORBAS) TUTIN

Croatian clove, Dianthus giganteus D´Urv ssp. croaticus (Borbas), the indigenous perennial, neo-endemic plant, was chosen out of the flora of the continental Croatia for the placement on the ornamental plant market. Basic prerequisites for the introduction into commercial growing of this attractive species were researched during the three year period of the project "Introduction of indigenous ornamental species into horticulture". Croatian clove could be used in ornamental horticulture for planting in private gardens and public spaces, as a pot flower or cut flowers. As a first step to introduce it into culture, methods and duration of plant propagation were researched. Seeds collected in natural habitats, were sown in unheated plastic greenhouse in two seasons (spring and autumn). It was determined that the sowing date doesn't make any significant difference for the growth parameters of the seedlings, like plant height and plant diameter as well as the number of shoots per plant, which gives us the possibility of growing this species during the year-round floriculture production.
