The Silene acaulis

This cushion, punctuated by bright pink flowers, is not a moss. The silene acaulis is one of the champions of adapting to the worst. The cushion-like form allows it to reduce day-time and night-time temperature variations that can be significant at these altitudes. Moisture will also be trapped in this hairy, small-leaved stem. The ancient decomposed leaves of the silène acaulis contain nutrients that will allow it to grow and to bloom. A taproot in the cushion’s core will allow it to cling to the steepest terrain.
