Sorbus americana – American mountain ash

View prices and availability
În zona sa naturală de creștere din nord-estul Americii de Nord, această specie se transformă într-un copac de dimensiuni mici sau medii. Este un arbore cu creștere lentă, cu un trunchi gri deschis și crengi strălucitoare de culoare brun-roșiatică. Acest lucru face ca acest copac să fie o priveliște izbitoare în timpul iernii. Frunza impunătoare este formată din 13 - 17 frunze lanceolate care devin galben-aurii toamna. Marginea frunzei este, de obicei, puternic zimțată. Inflorescența este formată din corimbi cu diametrul de aproximativ 16 cm. Florile individuale au o dimensiune de 0,5-0,7 cm și sunt albe. Urmează, toamna, fructe de pădure de culoare roșie-portocalie. S. americana seamănă foarte mult cu S. aucuparia, dar se distinge prin crengile de culoare brun-roșcată și prin frunzele ceva mai înguste de culoare verde-închis.
