What are the best gutters?

Wisteria can grow into a mound when unsupported, but is at its best when allowed to clamber up a tree, pergola, wall, or other supporting structure. Whatever the case, the support must be very sturdy, because old wisteria can grow into immensely strong and heavy wrist-thick trunks and stems. These will certainly rend latticework, crush thin wooden posts, and can even strangle large trees. Its pendulous racemes are best viewed from below. Wisteria is an aggressive grower which can quickly clog gutters, sometimes invade foundations, and cause other physical damage if not controlled. To avoid many of these problems, wisteria should not be planted near a dwelling.
