Hello everyone:

I know close to nothing about plants. I have no indoor plants because
of my two cats, one of which eats anything green. Eventually I'll get
some hanging plants they can't reach.

Meanwhile, I do have a patio with vertical iron bars -- I would love
to have plants out there that I wouldn't have to bring in during the
winter, and/or some ivy or vines that would twine itself around the
bars.

I'm in Washington DC, so we get every kind of weather. The patio is
mostly shady.

Any ideas? Thanks!
