Yuccas are exceptionally drought tolerant, not needing additional water once established in coastal California. They will however, grow faster, look more lush and bloom more if given water once they dry out. This yucca grows very quickly if given good drainage and summer water.

Growing Notes

This plant thrives in hot sun, but can also be grown in shade as long it does not get soggy. It will be more open and perhaps a bit floppy, but it also gets even more of a dusty blue glow. It is wonderful in a pot and can live out its whole life in a nice-sized pot.

Too shave or not to shave? Prune off the oldest leaves as they age to have a clean textured trunk, or leave an elegant skirt. If you choose to prune, this work is best done early and consistently, as it's easy to do when you can get your pruners under the leaves. But once they start to lie down on the trunk it becomes much harder. In high fire areas we recommend removing the skirt to reduce fire load, though as long as the fire isn't too hot, the skirt would just burn off as it does in nature.

A giant white flower spike emerges in summer. Once the flowers fade ,cut out the spike as low as possible. Your plant will go through a period of looking a bit scruffy, before hitting its stride again; sometimes flowering induces a second head and then later a fork in the trunk.
