Arbore grațios de mărime medie, cu o coroană piramidală regulată. Scoarța se desprinde de la o vârstă fragedă. Scoarța mai bătrână este de culoare brun-portocalie-roz și se desprinde puternic. Frunzele de culoare verde închis devin toamna de un galben butier atractiv, iar frunzele rămân pe copac cu aproximativ o lună mai mult decât la B. nigra. Înflorirea este timpurie, iar catrinii masculi lungi sunt foarte vizibili. 'BNMTF' a fost selectat pentru toleranța mai bună la secetă și la căldură decât B. nigra, un soi comparabil. În plus, copacul are o formă bună și regulată a coroanei.
