Rules of nature conservation and especially of biological diversity protection are reaching still more attention in landscape design. It has appeared that cleaning our environment from all kind of plants but these we are cultivating for food or other strictly determined purposes brought disaster for the nature and finally for our health and comfort. There is still more examples of designed green areas where you can find common or even ruderal plants. Such kind of aesthetics needs special approach to design. First step should always be the nature elements evaluation, which should recognise nature value of the area concerned and its surroundings. Introduced plants, if being expansive enough, are able to change and destroy valuable local plant communities. Second step is the selection of the places for common plants. Concerning importance of the area in urban structure and needed elegance should be established possible proportion of the area given for plant succession. Third thing is determining style of the aesthetic composition, shape of pattern forms etc. That step is strictly connected with overall composition of the area designed. Forth step is the choice of the plants. Preferred should be the plants naturally occurring in the region concerned. That is the safest way to protect local biological diversity. Plants designed for succession will be growing and success freely around. Some examples of proposals using succession of plants are given there. They are located in Chełm Śląski, Zabrze, and Sosnowiec in Poland.
