Another UFO and the neighbour who's growing it doesn't know either. It was the only flower (eye catching isn't it?) on the plant and the foliage looked like a lily of some kind. So can someone out there help with the name?
[edit 28/12/10 - the neighbour's daughter came through with a name - Blood Lily (scadoxus multiflorus), interestingly is considered to be rare and has many other names]
