Summary of the project "Urban private gardens" as spread of invasive plant species in the Czech republic with presentation of the current data. Common garden observations on selected alien plants cover mostly reproductive traits. The traits studied are plant height, seed production, propagule weight, epizoochory (external animal dispersal), terminal velocity of diaspores (anemochory), buoyancy (floating capacity), persistence of seed in the soil (type of seed bank), SLA (specific leaf area) and seedling establishment (germination under field conditions). Based on a large field survey of private gardens in the Czech Republic, we determined the frequency of planting of the studied species and whether the species have been reported to escape from cultivation. According to our preliminary results (for the subset of annual species), the most important traits related to the probability of escape fromb cultivation are plant height, followed by buyoancy of propagules, seedling establishment and terminal velocity. Suprisingly, the frequency of planting does not seem to influence the naturalisation success.
