Three-veined Anaphalis, or Himalayan Everlasting. A perennial from the Asteraceae family, native to the mountainous regions of the Himalayas, from Pakistan to China's Yunnan, where it grows between 2,000 and 4,500 meters in altitude on grassy slopes, rock gardens, and edges of clear forests, in conditions of intense light, proper drainage, and marked alternation between dry and wet seasons.

It forms upright and well-structured clumps, reaching 30 to 45 centimeters in height, whose most striking feature is its foliage: the leaves are lanceolate to oval, green on top and densely woolly-tomentose underneath with a pure silver white, presenting three well-marked main veins that earn it its specific epithet. The stems themselves are covered with a white woolly tomentum that gives the whole plant a very decorative silver luminosity, even when not in bloom.

The small, globular capitula are grouped in dense, flat corymbs at the top of the stems. The involucral bracts, of a pure papery white, persist long after flowering and are responsible for the plant's "everlasting" aspect: they do not wither and retain their bright whiteness, making the plant ornamental from July until the first frosts. At the heart of each capitulum, tiny yellow florets provide a touch of warm contrast. Remarkably, Anaphalis triplinervis is one of the few silver-foliaged plants that tolerates some soil moisture, which distinguishes it from most silver tomentum plants that require strict drainage.

In cultivation, it adapts to ordinary soils, even slightly cool ones, in full sun or light partial shade. It is hardy, easy, and spreads easily by clump division in the spring. It pairs remarkably with Echinacea, Penstemon, and ornamental grasses in summer beds, and makes an excellent cut and dried flower.
