A zinnia is the first ornamental plant to flower in space. This is part of the International Space Station's Vegetable Production System research. Although the primary aim is to produce fresh food on long missions, "space gardeners" have also reported how psychologically beneficial it is see and interact with live plants in this environment. News of the zinnia has been widely reported but with little mention of the variety. It was in fact a Profusion Orange. The Profusion series were developed by Sakata Ornamentals by hybridising Z. elegans and Z. angustifolia and have gained popularity around the world for heat, drought and disease resistance.
