Dryas octopetala. Mountain avens.

Life-form & Growth Form:  

Chamaephyte. Woody perennial. Extensively creeping, rooting at nodes. 

Flowering period: 

June & July.


Montane rocky outcrops, base-rich calcareous heath and limestone grassland. High- altitude sites on rocky outcrops and sea-level in Ireland. 


Over-grazing by livestock, particularly Feral Goats. Under-grazing can allow tall herb and scrub communities to shade plants. Hikers/walkers may trample some accessible plants. Natural processes including rock falls, bank slippage and soil erosion from cliff ledges. Climate change mahy over time cause more temperate plant species to increase their altitudinal range and so out-compete Arctic-alpine species such as Dryas. The disjunct nature of the three populations increases the risk of one or more becoming locally extinct.
