Chamerion dodonaei

Perennial of the Onagraceae family, this species is distributed in the mountains of central and southern Europe, from the Alps to the Carpathians and the Balkans, with some stations in the eastern Pyrenees. It is characteristic of mobile scree, torrent beds, and high-altitude alluvial gravels, generally between 500 and 2,000 meters, where it settles on poor, well-drained mineral substrates, often calcareous or siliceous.

It forms upright and slightly bushy clumps, reaching 30 to 60 centimeters in height, with thin and branched stems, which clearly distinguishes it from the straight and unbranched habit of Chamerion angustifolium. The leaves are very narrow, linear to linear-lanceolate, grayish-green, numerous and closely packed along the stems, giving them an almost grass-like appearance which is one of the most immediately distinctive features of the species.

The flowers, with four bright pink to magenta pink petals, are borne in loose terminal clusters. They are slightly smaller than those of the previous species but often of a more intense and saturated color. The fruit capsules produce silky white tufts at maturity, characteristic of the genus.

In its natural habitat, its flowering extends from June to August depending on altitude and exposure. In cultivation, it blooms from June to July.

A pioneer plant of open environments disturbed by water or landslides, it plays a stabilizing role on torrential alluvial gravels. Its very fine foliage and airy habit give it a visual lightness that contrasts with the usual robustness of colonizers of difficult environments.

In cultivation, it requires a very well-drained soil, poor to moderately rich, in full sun. It withstands summer drought well once established and is suitable for gravel gardens, ornamental scree, and compositions with a natural and mountainous character. Its propagation by rhizomes remains more moderate than that of Chamerion angustifolium.
