The dust bin man asked me if I wanted any flowering plants. He is cleaning out someone's garden a few houses away--someone who doesn't want to have a garden anymore.

Half an hour later he came with a few cuttings, which I planted on the roof deck. They are very pretty. I made a mental note to ask a friend in the know what those white flowers are called.

And then the dust bin man came with more. And more. And more.

Help!
