My bad. Know that picture I posted from my garden last month? The one of the supposed "grapevine"? Yeah, well, sometimes I'm a little slow on the uptake.
That, I've discovered, is a ridiculously healthy honeysuckle, in the process of growing at a phenomenal rate and keeps trying to leap over the neighbour's fence for a swim in their pool. I'm not disappointed. I love honeysuckle, they're very attractive to hummingbirds and the like, and it's about to explode blossoms all over the place. But that "oh, I am SUCH a dunce" moment of realization was cringe-worthy. D'OH.
