The plant Pelargonium radula (Cav.) L'Herit. was reproduced by a classical procedure, that is in vegetative way with use of green grafts. The important factors during growth were the way of obtaining the reproductional grafts, supstrate, water ballance, the temperature of air and substrates, light and phytopatological protection of the grafts. During reproduction we tested the effect that a growth hormone 6-indol- 3-butter acid (IBA) has on the growth of the plant Pelargonium radula (Cav.) L'Herit. Vegetative reproduction of the plant Pelargonium radula (Cav.) L 'Herit. with grafts, the use of herbal hormone auxin IBA did not provide desired results. It only increased the growth of the stalk and leaf stems, but not the quantity of leaves. In this way leaf mass does not increase and neither does the quantity of essential oil which can be extracted from it by water destilation. In order to determine the structure of the leaf of Pelargonium radula we made transversal cross-section of the leaf and leaf stock
