This type of plant is widespread in Pshavi and Khevsureti. The optimum latitude for its vegetation is 1800-2200 meters. Dominant species are ones from the Parsley family (Fam. Umbeliferae+Apiaceae). The most widespread of them is Sosnowsky’s Hogweed (Heracleum sosnowskyi). In South Khevsureti, it grows in Roshki’s moraine relief and in the area of the Gudani and Khakhmati villages. While in North Khevsureti it can be found in the areas of Khone and Khakhabo. Hogweed is quite a dangerous plant, in case of contact with skin it leaves a scratch which will soon turn into a sore and last for a long time. Inexperienced tourists often become victims of this plant. To avoid nettling, one must wear long trousers and keep out of the plants reach. Other representatives of tall herbs are: teasel, valerians, Aconitum, Delphinium, etc.
