Hi Marty you're right about blæst being wind. But efeu means common ivy (Hedera helix), so the same plant as your garden wall. Most of the discussion in the article is about the owner of the wall having cut back the ivy at the top of the wall, because he was having the roof repaired, as the old cinema was being turned into apartments. So they're sort of blaming him for making the whole ivy plant collapsing. But he says he had suggested they share the cost of having the wall growth removed because it was too big, but they refused the idea, so then he only cut back the part on the top which was in the way. The funniest part is the old guy who owns the car, he says he doesn't care about a few scratches and bumps on the car, he's just happy he wasn't near the car when it happened.
