Grass of Parnassus, Parnassia glauca, (also known as Bog- Star) was named after Mount Parnassus in central Greece. It is not a type of grass, but rather, belongs to the family Celastraceae and can be found growing in fens, bogs and swamps. The striking green lines on its petals guide flies, bees and other pollinating insects to the flower’s supply of nectar.
The structure of Grass of Parnassus’s flower is not typical. In between its five functioning stamens and five petals there is a whorl of five sterile stamens, each of which is three-pronged. The spherical tip of each prong mimics a glistening droplet of nectar. These stamens do not actually produce any nectar – they are there purely to attract pollinators. The actual nectar is located near the base of these false, or sterile, stamens. Only one of the five true stamens in the flower is active at any one time, with each producing pollen on average once every 24 hours.

Grass of Parnassus, also known as Bog-star, is a favorite flowering plant of mine for two reasons. One is because I enjoy saying its name — try it, it sounds quite regal. Secondly, the green lines, or bee guides, on the petals are a striking color which you don’t see all that often in flowers. Grass of Parnassus is in the Saxifrage family – not in the Grass family, as its name would imply. It typically grows in wet meadows. Apparently the name comes from ancient Greece; the cattle on Mount Parnassus ate this plant with relish, and thus it was deemed an “honorary grass.” (An Ambush Bug is perched on a petal, waiting and watching for prey.)
