Smart looking variegated Yucca - I doubt that the flower spike will have time to open before the frost gets it though.
I have seen a couple of Yuccas around here trying to flower this late too - must be something about the season that has caused this - to my mind at least - daft late flowering attempt. It would be nice to think that the weather would be kind to them - but it's already pretty cold here with several frosts - hope your neighbour's plant makes it, Shelagh.
