In 14 species of variegata plants, Acer negundo, A. platanoides, A. pseudoplatanus, Chlorophytum, Coleus blumeii, Cornus alba (var. Argenteo marginata), Evonimus radicans, Eleagnus pungens "Maculata", Hibiscus siriacus, Iris germanica, Ligustrum aureum, Ligustrum ovalifolium, Peperomia magnolifolia, Thuja orientalis, the concentration of various elements of mineral nutrition have been investigated as well as the content of pigments in different coloured parts of leaves. The achieved results have shown that leaf parts differently coloured, have very different concentration of elements of mineral nutrition and chloroplast pigments. Higher concentrations of N, P, K were present in whitish-yellow parts of leaves compared to the green ones in all the plant species. The opposite conclusion could be drawn when the concentration of Ca is concerned. The Mg concentration has varied the least. The content of pigments shows that the photosynthetic activity of different coloured leaf parts was different in favour of the green parts.
