Betula populifolia 'Whitespire' Betula populifolia 'Whitespire'

Arbore de talie medie, cu coroana piramidală regulată, fără lemn lateral greu. Crengile anuale sunt maro închis, iar scoarța mai veche este albă, nu se desprinde. Frunzele triunghiulare au vârful frunzei ascuțit și lung. Este verde proaspăt și devine galben auriu intens toamna. Pentru o lungă perioadă de timp, s-a presupus că "Whitespire" provine din semințe colectate în Asia. Ulterior, s-a constatat că a existat o confuzie în dosare și că "Whitespire" este un răsad de B. populifolia. Tolerează poluarea aerului și, prin urmare, poate fi utilizat în zonele industriale.
