White flowers, III–V, closely packed in cylindrical spikes, stalks white or green; mid-green foliage; height at least 1m; spread 75–100cm. Hardy.
Collected, according the Georg Dieck(Zöschen, Germany) in 1892, at about 1,400m altitude, in Serrania de Cuenca, Spain, more than a century ago. It is unlikely that more than one clone is in cultivation now, even if he collected several. Introduced by Georg Dieck in 1899.
Named from Latin alpinus = growing in the alpine zone of mountains.
