Ptelea trifoliata 'Glauca': 'Glauca' Common Hoptree: ENH-690/ST532, 3/2024

Abstract

This cultivar of the deciduous North American native tree reaches 15 feet in height with a spread of 10 to 15 feet and forms a broad, rounded canopy over a slender, grey trunk. The trifoliate, four to six-inch-long leaves are glaucous blue-green in summer, turning yellow in fall before dropping. Inconspicuous greenish-white flowers appear in terminal clusters in June and July, their presence easily detected by the delicious orange blossom-like perfume. The blooms are followed by interesting, one-inch-diameter, flattened, tan "wafers" which will persist on the tree if not first consumed by wildlife. In the past, this bitter fruit was used as a substitute for
hops in brewing beer. Original publication date November 1993.
