Yucca aloifolia in the rain. This yucca grows tall and can handle lots of neglect and water restictions. It flowers white similar to Y. recurvifolia. This specimen has a pup and is expected to form a clump over the years.

Vancouver Island is home to new yuccas because of growing interest to save water in dry summers from Victoria to Nanaimo.
