Herbaria, which document plant life on Earth, continue to grow in number and the number of specimens they hold. Digitization has increased the accessibility and utility of herbarium specimens, but many herbaria lack current information, and some are being consolidated or moved to offsite storage. Partnerships are crucial for the future health of herbaria. The article proposes reimagining herbaria as a global resource rather than independent institutions, and encourages herbaria to embrace Team Science principles to promote their holdings for research and conservation projects. Key initiatives include the "One Herbarium" concept, which aims to unite herbaria globally, and the creation of an Extended Specimen Network to link herbarium data with other biological and environmental datasets. These efforts can enhance the reach and impact of herbarium specimens in understanding biodiversity and addressing conservation challenges.Herbaria, which document plant life on Earth, continue to grow in number and the number of specimens they hold.
