Etymology –
The term Valerian comes from the medieval Latin valerian, attested from the 10th century, at the origin of the vulgar name in many European languages ​​including Italian, of a disputed etymology; the most accredited hypothesis traces it back to the diocletian province Pannonia Valeria, in western Hungary, where the plant would have been abundant; others connect it to the verb to be in good health, due to its officinal virtues (more likely a case of a posteriori paretymology); others to different characters named Valerius or Valerianus; others derive it from ted. baldrian (and not vice versa), which could be connected either with the god of light Baldur or with the hero Wieland, alluding to the magical properties of the plant as a demon-warder.
The specific epithet phu comes from φυ phu, a Greek interjection that manifests disgust, nausea: in reference to the intense smell of the plant.

Geographic Distribution and Habitat –
Valerian phu is a native plant of Europe and northern Asia.
Its habitat is that of humid soils such as the banks of rivers, woods, prairies, clearings of wetlands throughout Italy, in the Alps and the Apennines, up to 2400 m.

Description –
Valeriana phu is a herbaceous plant with erect and very branched stems, up to 100 cm, which bear light yellow spring foliage.
These opposite leaves then acquire a greener color by June.
The flowers are gathered to form a particular type of inflorescence called corymb; they are hermaphrodites, with reduced calyx and corolla with 5 petals, tubular and creamy white in color; the androecium is composed of 3 stamens, the gynoecium by a tri-carpellar pistil with an inferior and unilocular ovary. Flowering occurs in July-August and pollination is entomogamous (through Insects).
The fruit is a striated achene with feathery bristles deriving from the modification that the small teeth of the calyx undergo with maturation. Their presence helps their dispersion by means of the wind.

Cultivation –
Valerian phu is a perennial herb prized for its pale yellow foliage and erect, branching stems.
It can be grown in rich and cool soils, with good humidity and also adapts to the sun if the humidity is satisfactory.
It is an ideal plant for semi-shaded flower beds and bright undergrowth.
When arranging flower beds, it should be planted with distances between the plants of 60 cm.
Propagation occurs by seed.
