Moss Campion Adaptations

Mostly, the Moss Campion appears in the Rocky place of Alpine Tundra and high Mountains. To survive in harsh environments, Alpine tundra plants have developed particular adaptations. Those adaptations are

  • Protected leaves and buds: Most of them have small, ground-hugging leaves and buds hidden inside the foliage for optimal protection. This helps in retaining their moisture and protects them from drying out.
  • Slow growth: Moss Campion grows very slowly. They produce their own warmer climate inside the cushion when the bright sun ray falls into it.
  • Compact tussock: It has a compact tussock and prostate. Those help them to compile the heat from the sun. Not only that, but this also helps in their protection from harsh wind and frosting weather.
  • Moisture absorption: They can absorb moisture from the ground when needed.
  • Nutrient collection: It collects nutrients from the air for its growth.
  • Grows in wet soil: They prefer moist soil because they have no roots and can dry out wholly if there is no rain or water.
