Mountain avensDryas octopetala

Dryas octopetala, commonly known as mountain avens, is a low-growing evergreen shrub native to arctic and alpine regions of the Northern Hemisphere. It is easily recognized by its distinctive white flowers with eight petals—an unusual trait in the rose family, where it belongs. The plant’s name Dryas refers to Greek tree nymphs, evoking its woody, ground-hugging form, while octopetala highlights its characteristic petal count. Adapted to extreme climates, it thrives on cold, wind-scoured limestone and gravel slopes, where few other flowering plants can survive. Its presence often signals ancient, nutrient-poor soils shaped by glaciation, making Dryas octopetala a botanical hallmark of high mountain and tundra ecosystems.
