Dryas

a genus of plants of the family Rosaceae. They are procumbent evergreen shrubs with leathery leaves, glossy above and tomentose below. The flower stalks are erect, and the solitary, large flowers are white or sometimes yellow. There are usually eight or nine petals and sepals, and numerous stamens and pistils. There are more than ten species, growing in arctic and subarctic regions and in high mountains in the northern temperate zone. In the USSR about ten species may be found in tundras, barren places, and alpine meadows. The most widespread species are D. octopetala and D. punctata. The plants of this genus are used in landscaping small “alpine” hills.

For decades, scientists speculated that a comet could have caused the drop in temperature that occurred during a period known as the Younger Dryas. This period is crucial in the history of humanity as it is pinpointed as the era during which agricultural practices began and the first Neolithic civilizations made their mark.

My analysis of the long-term phenology monitoring data from Tanquary Fiord showed that the midsummer-flowering mountain avens (Dryas integrifolia Vahl) has significantly advanced its flowering and fruiting times over the 20 years of monitoring, while the early spring-flowering purple saxifrage {Saxifraga oppositifolia L.) has not (Panchen and Gorelick, 2015).
