I carefully planted hops and a grape vine to climb up poles from the earth onto the trellis covering the elevated front deck. The grape started climbing and then got stripped by caterpillars. One of the hops has reached about 10' and slowed down as if awaiting instructions. But something I did not plant has really taken off. It is coiling on the deck planning its takeover. Extensive googling turned up the name Cyprus Vine, and it is loved and hated because of its vigor. It has the softest fern-like leaves, and bright red five-pointed star flowers in profusion.
For Derrida true hospitality (if there is such a thing) happens when you even welcome the stranger who may destroy your house. Welcome Cyprus Vine! But I think I will keep a watch on it.
