This is why we bought one.

I seem to remember mentioning a hunt for Viburnum Farreri recently.
I'd hate to state categorically that "this is it", but it's certainly sufficiently like it to use as an example of why we wanted one.
It's yet another reason to wish we had smellivision because, while you can see why we wanted one you can'e smell the other reason.
I spotted this down DeWhelpdale Lane because ours was flowerless when we bought it.
