Zanthoxylum americanum – Prickly-ash, Toothache tree

View prices and availability
Crește de la o formă de arbust la un copac mic, uneori cu mai multe tulpini, cu o coroană rotundă. Pe crengi, sub fiecare mugure sunt plasați doi spini. În scoarța veche, acești spini sunt uneori încă vizibile sub forma unor cocoașe mici. Frunzele impare-penate constau din 5 până la 11, uneori 13 foliole ovale până la ovoidale de culoare verde închis. Pe fusul frunzei există întotdeauna 1 sau 2 spini de care sunt atașate foliole. Fascicolele axilare de flori galben-verzui apar înainte de dezvoltarea frunzelor și nu sunt foarte vizibile. Acestea sunt urmate de fructe negre. Acestea sunt aromate, au un gust foarte ascuțit și un efect narcotic. Se spune că indienii mestecau fructele atunci când aveau dureri de dinți. Arborele își datorează astfel denumirea americană-engleză Toothache tree. Este un arbore de parc destul de discret, potrivit pentru plantații defensive. Are puține cerințe față de sol și este foarte rezistent.
