Apparently the classic Italian pergola had masonry columns with grape as the plant element.
Neither grape nor wisteria will grow in our climate. One type of Virginia creeper and the wild yellow clematis grow here, but they are green for only three months and bare and forbidding the rest of the year.
So we are safe from female desires for pergolas, but instead they demand a structure for weaving, greenhouse or some such. Think solid structure with R-40, double or triple glazing, gas heating and plumbing.

Just envy; the pleasures of green structures are denied us here.
