Nome comune: fusaggine, berretta del prete, corallini
Specie: Euonymus europaeus L.
Famiglia: CELASTRACEAE
Pianta da cespugliosa ad arbustiva, può raggiungere anche i 3 m di altezza.
Ha fusti a sezione quadrangolare, con foglie lanceolate, opposte, a margine finemente seghettato ed apice molto appuntito.
- I fiori sono piccoli e bianco-verdastri a quattro petali, con odore un po’ sgradevole, riuniti in infiorescenze che si sviluppano a partire dalle ascelle delle foglie.
- Le foglie sono picciolate, opposte, ellittiche o lanceolate a margine finemente dentato. Il colore della pagina superiore della foglia è verde scuro, quello della foglia inferiore più chiaro.
- Il frutto è una capsula a quattro lobi, di colore da rosa-arancio a rosso corallo.
- I semi della fusaggine dopo l’apertura del frutto, giunto a maturità, penzolano caratteristicamente nel vuoto appesi a sottili filamenti.
In autunno è inconfondibile per i frutti, di colore rosa-arancio, rosso corallo intenso, dalla caratteristica forma a quattro lobi, che li fa assomigliare al vecchio cappello dei preti (da cui il nome popolare).
Tossicità
La letteratura del settore indica che praticamente tutte le specie del genere Euonymus sono velenose.
I componenti tossici sono presenti nella corteccia, nelle foglie e nei frutti.
Questi, per il loro colore particolarmente attraente, rosa-arancio, rosso corallo intenso, sono notevolmente invitanti per i bambini, per i quali l’ingestione può rivelarsi anche mortale.
Cavalli, pecore e capre che bruchino le foglie di fusaggine possono parimenti rimanere avvelenati.
I primi sintomi dell’intossicazione compaiono 12-16 ore dopo l’ingestione.
In passato la polvere ricavata dai coloratissimi frutti, fatti essiccare, veniva utilizzata contro la scabbia e anche come insetticida contro i pidocchi.
I semi della fusaggine sono appetiti dagli uccelli che ne sono particolarmente ghiotti.
Curiosità
Il nome popolare di fusaggine deriva dall’utilizzo del legno del fusto di questo arbusto per costruire i fusi per filare la lana.
I giovani fusti, inoltre, sono particolarmente elastici e per questo sono stati utilizzati anche per costruire archi.

Euonymus europaeus, the spindle, European spindle, or common spindle, is a species of flowering plant in the family Celastraceae, native to much of Europe, where it inhabits the edges of forest, hedges and gentle slopes, tending to thrive on nutrient-rich, chalky and salt-poor soils. It is a deciduous shrub or small tree.
Description
Euonymus europaeus grows to 3–6 m (10–20 ft) tall, rarely 10 m (33 ft), with a stem up to 20 cm (8 in) in diameter. The leaves are opposite, lanceolate to elliptical, 3–8 cm long and 1–3 cm broad, with a finely serrated edge. Leaves are dark green in summer. Autumn colour ranges from yellow-green to reddish-purple, depending on environmental conditions.[2]
The hermaphrodite flowers are produced in late spring and are insect-pollinated; they are rather inconspicuous, small, yellowish green and grow in cymes of 3–8 together. The capsular fruit ripens in autumn, and is red to purple or pink in colour and approximately 1–1.5 cm wide. When ripe, the four lobes split open to reveal the orange seeds.
Habitat and ecology
E. europaeus occurs as an understory shrub or small tree primarily in old hedgerows, open woodland clearings and margins, and scrubland on base-rich or calcareous soils, although it is also shade-tolerant. It rarely invades open habitats such as grasslands except in the presence of abundant hedges[3] In Ireland, it can also be found growing on rocky limestone outcrops, rocky lake shores and limestone pavements.[4]
It is typical in Fraxinus excelsior – Acer campestre – Mercurialis perennis woodland (W8), and it is a frequent companion of Cornus sanguinea in open-stand scrub over limestone, generally in low frequency and abundance throughout.[5] It is usually scattered in distribution but may occasionally occur remarkably commonly on a local scale, such as in the so-called "Spindle Valley" in the Chilterns.[6] The scattered distribution is likely limited by dispersal of seeds via birds and rodents.[7]
E. europaeus is the almost exclusive winter host of the black bean aphid.[8] Because of the potential economic loss from this insect that feeds on cultivated broad beans and sugar beet, spindle in the past was commonly removed from hedges and woodlands as a measure against black bean aphid outbreaks and agricultural yield losses, although this widespread removal does not appear to have impacted current populations. In 1944, The Biology War Committee also began a campaign to investigate the distribution and ecology of E. europeaus as a basis for aphid control measures.[3]
Cultivation and uses
It is a popular ornamental plant in gardens and parks due to its bright pink or purple fruits and attractive autumn colouring.
In cultivation in the UK, the cultivar 'Red Cascade' has gained the Royal Horticultural Society's Award of Garden Merit.[9][10]
European spindle wood is very hard, and can be cut to a sharp point; it was used in the past for making spindles for wool-spinning and for butchers' skewers.[11]
Charcoal produced from this plant is seen as superior among artists due to its strength and density.
Parts of the plant have been used medicinally.[12] However, the fruit is poisonous, containing, amongst other substances, the alkaloids theobromine and caffeine, as well as a large number of much more toxic substances, including cardiac glycosides, and an extremely bitter terpene. Poisonings are more common in young children, who are enticed by the brightly coloured fruits. Ingestion can result in liver and kidney damage and even death.[13]
