英文摘要	Urbanization coupled with climate change results in significant stormwater management challenges. In this context, the use of green infrastructures such as bioswales and bioretention systems to intercept, slow down and filter runoff has been increasing in North America in recent years. However, little data is available on the selection of optimal plant species adapted to cold climates, their optimal positioning in the swale and intra and inter-seasonal variation in plant growth. A field experiment was conducted during three growing seasons from July 2020 to August 2022 in a proximal suburb of Quebec City, Canada, to monitor the survival rate. Growth (height and plant area), and floridity (number of flower buds and flower stems) of 22 plant species in 48 cold climate bioretention cells located along streets. The study aimed to understand the influence of planting position (margin: upper position, usually dryer; slope; middle position, fluctuating water conditions; bottom: lower position, usually moister) on species development, in order to identify the species most and least adapted to the different moisture conditions. Results showed that survival was generally high (> 86%) and was not affected by position within the bioretention cells. However, for most species, plant area increased, and height decreased at the margin compared to the slope position, while floridity only increased at the margin for four species (Heliopsis helianthoides (L.) Sweet, Coreopsis verticillata L., Hemerocallis 'Stella Supreme L., Verbena hastata L.). Seven species (Campanula carpatica Jacq Alba, Hesperis matronalis L., Osmundastrum cinnamomeum (L.) C. Presl, Rudbeckia hirta L., Verbena hastata L., Cerastium tomentosum L., Athyrium filix-femina (L.) Roth ex Mertens) exhibited lower survival and growth rates over time than the others. Overall, 15 out of 22 species performed well in the bioretention cells with minimum maintenance over the course of the experiment. Results also showed that plant area at the end of the growing season was much more influenced by position in the bioretention cells than were height or floridity, while survival was not influenced by this factor. A better knowledge of plant interactions in varying spatial distribution over time can contribute to improving and potentially maximizing bioretention performance.
