Honeysuckle

Early afternoon, when the rain stopped briefly, I went for a short walk. I was surprised to spot this honeysuckle plant growing over a fence, still happily blooming away! It's definitely not a "proper" winter-flowering Lonicera, but a spring/summer flowering species.  
One of our neighbours put a notice on our road's WhatsApp saying he had an old unwanted Belfast sink going for free. Guess what, it's now in my garden! I couldn't resist. Now to decide, over the winter, whether to grow herbs in it, or make it into an alpine trough. I have read about making and applying hypertufa to such a sink, to give it a stone-like appearance, which could be the way to go. All suggestions welcome!
