Tai viena didžiausių pušų pasaulyje, savo dydžiu nusileidžianti tik saldžiajai pušiai. Vidutiniškai ji siekia 30-50 metrų aukštį, o Šiaurės Amerikos vakarinėje dalyje, kur auga natūraliai, užfiksuotas 81,7 m aukščio rekordas. Tai gana sparčiai auganti rūšis, formuojanti tankią ir gilią šaknų sistemą, todėl yra atspari vėjams. Laja siaura. Kamienas rudas, kiek oranžinės spalvos. Senesnių medžių žievė išilgai skeldėja. Spygliai susitelkę po 2-5 (tai priklauso nuo porūšio), jie ilgi 12-25 cm ilgio, ploni, žalios spalvos. Kankorėžiai 8-15 cm ilgio, pailgi, rudos spalvos. Jie bręsta kas 3-5 metus, o gausus jų derlius būna kas 8 metus. Gerai auga derlingoje, drėgnoje, tačiau gerai drenuojamoje dirvoje. Nepakantus užmirkimui. Tai šalčiams atspari rūšis, nors kartais nukenčia nuo didžiųjų šalčių ar šalnų, tačiau jau artimiausiu vegetacijos sezonu atsigauna ir sėkmingai auga toliau. |
