As plants@work celebrates its 25th anniversary, this three-part series explores the 25 houseplants that have played the biggest role in transforming workplaces over the past quarter of a century. Drawn from 25 years of Leaf Awards entries, these are the plants that plants@work members have relied upon to create healthier, happier and more productive working environments across the UK.
