Lewis, E., Phoenix, G. K., Alexander, P., David, J., & Cameron, R. W. (2019). Rewilding in the Garden: are garden hybrid plants (cultivars) less resilient to the effects of hydrological extremes than their parent species? A case study with Primula. Urban Ecosystems, 22(5), 841-854. Full Article.
From Conclusions section: “Cultivars dominate many designed landscapes including public and private gardens. Despite this, relatively little is known about their ability to tolerate the hydrological extremes that are likely to become more frequent in the near future. Our research in both controlled and garden experiment settings found strong evidence to suggest that highly-cultivated taxa ofPrimulaare more susceptible to extreme stress (including both waterlogging and drought). If many cultivated forms of garden/landscape plants prove to have limited tolerance to the effects of climate change (such as more radical oscillations in soil moisture availability), even when maintained in highly-managed landscapes, then the implications are significant. The loss of a high proportion of cultivated plants (and as this paper also implies, less generalist species) from gardens and parks would have an immense impact on the floral diversity of such landscapes, and in terms of public/heritage gardens undermine the viability of many. Thus a key consequence of this research is a call for ornamental plant breeders to give much greater consideration to stress tolerance when breeding and selecting new cultivars.”

Excerpt: “The number of current horticultural tree species with suitable climate within Australia’s SUAs is predicted to progressively decline as climate change intensiﬁes, with more pronounced reductions in urban areas which are currently warmest.”
