Abstract
The experiment was carried out in 2004-2006 at the Experimental Farm of the Department of Vegetable and Medicinal Plants Cultivation, University of Agriculture in Lublin. The study was aimed at the evaluation of growth and development of two leuzea species: Leuzea carthamoides DC and Leuzea centauroides L. cultivated under Polish climatic conditions. Observations were made upon annual, biennial, triennial, and quadrennial plants. The leuzea plantation was set from seedlings produced in a greenhouse. Leuzea carthamoides DC plants were higher and produced more leaves. Leuzea carthamoides DC and Leuzea centauroides L. plants formed inflorescence stems and bloomed in the second year of cultivation. Inflorescence stems in Leuzea carthamoides DC are single, while those in Leuzea centauroides L. are branched. Leuzea carthamoides DC plants form larger heads compared to Leuzea centauroides L.
