“…With the growing public awareness of ecological conservation, spontaneous plants that can thrive in urban environments, possess ornamental value, and provide ecological benefits have attracted significant attention 1 . Spontaneous plants demonstrate traits of robust adaptability, low maintenance requirements, and wide distribution 2 , making them a crucial element of urban plant diversity and essential for establishing sustainable, low-maintenance plant landscapes 3 , 4 . Despite their significance, native self-dispersed species are underutilized in urban greening initiatives.…”

The spontaneous plant landscape is a key focus in the development of urban environments. While many spontaneous plants can coexist with bryophytes to create appealing wilderness landscapes, the potential allelopathic effects of bryophytes on the growth of neighboring spontaneous plants remain uncertain. This study evaluated the allelopathic impact of Thuidium kanedae aqueous extracts on the germination and seedling growth of prevalent urban spontaneous plants by analyzing seed germination, seedling growth morphology, and associated indices. We also investigated the allelopathic potential of the predominant compounds in the extract on seed germination. Our findings reveal that the aqueous extract significantly impeded the seed germination of Ophiopogon japonicus, Taraxacum mongolicum, and Viola philippica, with the level of inhibition correlating positively with concentration. In contrast, Senecio scandens seed germination showed a concentration-dependent reaction, with low concentrations promoting and high concentrations hindering germination. The extract consistently reduced root length in all four species, yet it appeared to increase root vigor. The chlorophyll content in O. japonicus and V. philippica seedlings reached a maximum at a concentration of 5 g/L and decreased with higher extract concentrations. The treatment resulted in elevated catalase and soluble protein levels in the seedlings, indicating that the extract induced stress and enhanced the stress resistance index. L-phenylalanine and 2-phenylethanol, substances present in the extract, were notably inhibitory to seed germination across all species, except for O. japonicus. Notably, 2-phenylethanol exhibited a stronger allelopathic effect than L-phenylalanine. Allelopathy synthetical effect evaluation showed that high concentration of aqueous extract allelopathic inhibition effect on seed germination of four plant species, but allelopathic promotion effect on physiological and biochemical growth of Taraxacum mongolicum, Senecio scandens and Viola philippica. In summary, the study demonstrates that bryophytes exert allelopathic effects on neighboring spontaneous plants, with the degree of influence varying among species. This suggests that the germination and growth of spontaneous plant seeds may be selective in bryophyte-dominated habitats and that the density of bryophytes could shape the evolution of these landscapes.

The aim of the study was to summarize the use of synanthropic vegetation in public green areas of selected Polish cities. The study included issues related to phytosociology and landscape architecture. For this purpose, a literature study was performed. Part 1 identified possible ways of using synanthropic vegetation in the design of public green areas, Part 2 showed examples of such areas from Warsaw. The authors suggested species that can help enrich urban lawns, part 3 contains proposition of plant species composition for more natural lawns in city parks, including synanthropic plants typical for Poland (prepared by the authors). The process of gradual introduction of synanthropic vegetation in Poland was summarized and compared to the trends in Western European countries. The urban policy of Warsaw regarding the mowing of lawns and the use of flower meadows was briefly described, which influences the presence of synanthropic species in the urban environment. A watershed moment for the use of synanthropic species in Poland was identified, as well as the authors‘ predictions for their future use.

Synanthropic flora (weeds, i.e., spontaneously developed plants) are plants that accompany humans, appearing as a result of anthropopressure as well as after its cessation. The potential of synanthropic flora in shaping green areas usually brings many measurable benefits that depend on land management in cities. This study aimed to determine the preferences and attitudes of adults towards synanthropic flora in settlement units. This article presents survey results from 447 city residents. The obtained results were statistically analyzed using the k-means clustering method to identify segments of respondents with similar attitudes and preferences toward synanthropic flora. Mann–Whitney U tests were employed to determine statistical differences in the demographic variables among the analyzed clusters of respondents. Additionally, multiple regression analysis was performed to identify the opinions and attitudes towards synanthropic flora that may influence their greater acceptance in the vicinity of residential areas. The results obtained in the multiple regression analysis indicate that the respondent’s evaluation of the level of support for the introduction of more synanthropic vegetation into urban greenery (Yw) grows with the increase in the acceptance of synanthropic plants’ occurrence in the surroundings. Residents’ acceptance of synanthropic flora in green areas is at a relatively high level.
