Didymosphenia geminata, commonly known as didymo or rock snot, is a species of diatom that produces nuisance growths in freshwater rivers and streams with consistently cold water temperatures and low nutrient levels.
Meaning from Greek Mythology. The legend and meaning of the peony goes all the way back to Greek mythology. It is believed that the peony is named for a person of healing named Paeon who was a student of Asclepius, the god of medicine and healing.
Plant herbaceous peonies so the buds are 2 in. (5 cm) from the surface. Place the clump of peony tubers in the hole, with the small buds or eyes pointed upward, and the long roots pointed downward. The buds should be no more than 2 in. (5 cm) from the surface, or the plant may fail to emerge.
