One wisteria species is named for Longwood Gardens, PA. It is hardy in the eastern United States along with related species. They bloom in May. I noticed no fragrance but there may well be such.

Japanese Wisteria at Longwood Gardens
At Longwood Gardens in Pennsylvania very close to the border with Delaware are
wisteria vines trained in three sunken enclosures, into tree-like, tiered forms, designed in 1976. Fragrant.
