The 2026 Royal Horticultural Society (RHS) Chelsea Flower Show has concluded, showcasing a significant pivot in horticultural trends that are expected to influence global gardening practices. According to reports from the show, there is a marked transition toward functional plants, such as those used for natural dyes, and a continued preference for perennials over annuals.
A major point of contention at this year’s event was the introduction of gardens designed entirely by the AI application ‘Spacelift’. While the technology’s developers argue that the tool democratizes garden design for those unable to afford professional services, the move sparked protests among human designers, with some labeling the automation a “betrayal” of the collaborative creative process. This development has prompted industry experts to urge horticultural professionals to monitor how AI algorithms might influence future plant breeding and marketing trends.
Other notable trends included the “edimental” movement—integrating edible plants like wheat and cabbages into ornamental landscapes—and a notable lift of the historic ban on garden gnomes. The RHS signaled that these changes are part of an effort to make gardening more accessible and inclusive for a wider audience.
