Yucca flaccida 'Golden Sword' (Golden Sword Yucca)


Michael's Opinion

This Yucca is a tough plant suitable for very dry areas where the soil is poor. 'Golden Sword' is one of the more attractive cultivars and I have used it to good effect in contemporary landscapes. I once tried to kill a Yucca flaccida growing in my own garden. It involved digging, using the lawn mower and finally parking the truck tires over it when it reappeared in the drive.
