The growth capacity of annual vines can be just this side of scary. Giant woolly morning glory, Argyreia nervosa, can climb thirty feet in a Summer—and that's just during New England's comparatively brief and cool one. In its native India? Maybe twice as high. Madeira vine, Boussingaultia basseloides, is another tree-smothering terror where hardy, but is merely exuberant here.
Moonvine, Ipomoea alba, aspires to similar heights, racing twelve feet high in August, then waving around for even higher conquests.
But then came the possibility of a visit from Hurricane Hermine: Time for the white guy-lines in the picture. My fourteen-foot tripods could handle thunderstorms, but not gales that might tumble the patio furniture. Ah, the suspense before the storm's arrival.
