Pearlwort is a perennial with an active and short growing, blooming and seed developing period. It becomes inactive in winter. It tolerates extremely cold and dry conditions, and when frozen decreases photosynthesis to about 30-40% of its most active rate.
A blanket of snow aids in its photosynthesis. Its leaves are small, minimizing moisture loss, its root system shallow to support it in thawed ground, its cup-shaped flowers direct sunlight into the flower's center.
It grows in small, short clumps to protect it from wind, ice particles and cold. It produces is own 'uniform coverage of flavonoids' to protect it from UVB radiation in summer.
