More about this plant
Green Pillar is a fastigiate selection of pin oak with an upright, narrow, columnar crown, reaching 50 to 60 feet tall but only 12 to 15 feet wide because its branches do not droop the way the species does. The glossy dark green leaves have five bristle tipped lobes and U shaped sinuses and turn maroon red in fall, and small round acorns ripen in October and November. It is fast growing, wants full sun and a well drained acid soil, and becomes drought tolerant once established. The narrow habit makes it useful as a specimen, a deciduous hedge or a promenade tree where there is no room for a wide crown.
