Ptelea trifoliata (Hop tree)
Ptelea trifoliata, the hop tree, is an attractive small (growing to 6m) US native plant, where its seeds were used as a substitute for hops. It's in the citrus family, and, accordingly, is aromatic. This must account for two of its synonyms, stinking ash and skunk bush - neither thought up by the marketing department. Relatively disease free and easy to grow, will tolerate most conditions - it grows naturally on rocky mountainsides. It's slow into leaf, which is helpful in areas with late frosts. Honeybees love its yellow flowers, which are helpfully out during the "June gap". Its value for solitary and bumblebees is uncertain. Ptelea trifoliata 'Aurea' has decorative yellow leaves, and we charge an extra £10 per plant for it.
