Ornamental plantations are characteristic of a wide range of man-made habitats such as gardens, parks or urban spaces. Nowadays, low-maintenance perennial beds are becoming popular in horticulture and urban planning. Due to low levels of management and good records of initial plantation, perennial beds are suitable for studying vegetation processes such as competition amongst garden ornamentals and succession. We studied perennial flowerbeds in the Czech Republic that had a known initial composition at the time of establishment in 2006–2010 and we compared this with their state in 2016. We aimed to assess (i) how planted ornamental assemblages changed during 10 years of succession, and (ii) whether initial assemblage composition determined the pattern of change. We observed a decrease in biodiversity from initial plantation to the recent state across all flowerbeds in the experimental garden. In terms of diversity and stability, species-rich assemblages, mostly composed of taxa native to prairies, were the most stable. The most successful taxa (i.e. reaching high abundances with good persistence) originated from North American and Mediterranean regions.

多年生人工林中本地植物和外来植物的组合变化：草原物种稳定了社区组成

观赏人工林是各种人造栖息地的特征，例如花园，公园或城市空间。如今，低维护的多年生病床在园艺和城市规划中变得越来越流行。由于管理水平低和初期种植的良好记录，多年生病床适合研究植被过程，例如园林观赏植物之间的竞争和演替。我们研究了捷克共和国的多年生花坛，该花坛在2006–2010年建立时的初始成分已知，并将其与2016年的状况进行了比较。我们的目的是评估（i）种植的观赏植物在继承10年后如何变化；以及（ii）最初的组装组合是否确定了变化的模式。我们观察到实验花园中所有花坛的生物多样性从最初的种植到最近的状态都在减少。就多样性和稳定性而言，物种丰富的组合最为稳定，这些组合主要由大草原原生的分类单元组成。最成功的分类单元（即具有良好持久性的高丰度）来自北美和地中海地区。
