One of the partners of the project, VÚKOZ, in 2023 implemented several plantings of alternative "safe" species on flowerbeds in cities. During these plantings, the properties and possibilities of using alternative "safe species" of plants were verified. Several combinations (mixtures) of perennials with incorporated alternative species have been proposed. Together with SZÚZ, a demonstration planting was carried out in Mělník (Horticultural Academy) using one of these perennial mixtures. It was also used in demonstration plantings in Brno and Ostrava.
Another four newly created combinations (mixtures) were used in demonstration plantings implemented by VÚKOZ, of which one in the village of Klokočná (community planting in cooperation with local residents) and three on experimental beds in the Dendrological Garden in Průhonice.
In all cases, these were extensive perennial plantings in a flower bed made of gravel, sand or a structural substrate, in which individual plant species are divided into groups according to their function in the community (solitary, group, interspersed, cover and bulbs). Beds, or specific combinations of plants have been designed to minimize their care (the mineral layer reduces drying and weed growth). Not only promising alternative ("safe") species of perennials were used in the mixtures, but also species tolerant to drought and supporting pollinators.
