Olten plant exchange draws collectors with cuttings costing 1,299 francs

Cuttings priced at more than 1,000 francs were among the plants offered at Plantswap, Switzerland’s largest plant exchange, held in Olten in the canton of Solothurn. SRF reported that more than 30 exhibitors presented plants and cuttings at the weekend event.

The exchange at the Schützi venue attracts dedicated houseplant fans. Alongside familiar species such as pothos and monstera, exhibitors offered valuable rarities. Monsteras were also available with unusual leaf colourings rather than simple green leaves.

Plantswap co-organiser Janine Küfer said visitors could be divided into three main groups: orchid enthusiasts, cactus and succulent collectors, and the aroid group, which focuses on classic houseplants.

According to Küfer, older people are particularly interested in orchids, cacti and succulents. That community declined during the coronavirus pandemic because it was less connected through social media, she said.

Houseplants, by contrast, became increasingly popular among younger generations during the pandemic. The audience at the exchange reflected that trend, appearing young, urban and fashionable.

Küfer herself discovered her interest in plants during the pandemic. She began ordering and sending plants across Switzerland through Facebook groups. A planned meeting with 15 people instead attracted 150, giving rise to the exchange.

Research links plants with wellbeing

The effects of houseplants on psychological wellbeing have not yet been extensively researched, although social science findings in the field have grown significantly over the past 20 years.

Environmental psychologist Nicole Bauer said the positive effects of nature on human wellbeing were well established. Spending time in nature can help people recover and reduce stress, and experiencing nature can even lessen mental illnesses such as depression, she said.

A study from the Netherlands found that office workers felt better when potted plants were present. They reported fewer sick days and greater satisfaction with their performance.

Similar positive effects were found among school pupils. Surrounded by plants, they were able to concentrate better and their academic performance improved.

Bauer also highlighted the role of caring for a plant. When a plant is doing well, she said, its owner can feel responsible for that success, leading to feelings of satisfaction and calm. A study from Taiwan reached the same conclusion.
