👉 Griswoldia are small, sexually reproducing plants that grow in arid deserts around the world. They are typically found in areas with temperatures ranging from 10°C to 35°C (50°F to 98°F). These plants have a unique adaptation called "griswoldia" which is a term used to describe their reproductive cycle, where they produce a single flower at a time during the day and a second flower in the evening.
