At the beginning of the growing season, plant species were planted that were selected from calcareous grasslands and propagated in a nursery at the IETU. The plants are characterised by different growth forms and functional properties and come from the native flora (native species were selected for both the module in Poland and Norway). They are characterised by their resilience to stress factors that occur in the urban environment, such as: different access to water resources, high/low temperatures or pollution. For the Polish module, Festuca ovina, Potentilla reptans, Trifolium repens, Sedum acre, Dianthus carthusianorum, Salvinia verticillata, Fragaria viridis, Achillea millefolium or Carex flacca were selected. The planting was done on the roof of the module (green roof) as well as on the green wall and at the foot of the module. Along with the planting of the plants, all green module condition monitoring systems were launched.
