American wisteria

A friend gave me what appears to be an American wisteria so of course I planted it at Cherokee on faith that an arbor sturdy enough for this vine would appear before the vine overruns the bed! My hope is that a bench/arbor at the back of the bed can not only host this vine but give the students a place to sit and observe butterflies in the butterfly host plants in front of the bed or consider color theory in this mix of perennials. They can also observe the differences between Chinese and American wisteria and consider why we have so many plants so similar to plants from China. They may even study the Arnold Arboretum in Jamaica Plain Massachusetts for its mission to collect plants from China that will grow in Massachusetts. But I still need that arbor, anyone up for carpentry?
