Zone 4 to 11
Yucca filamentosa, commonly called Adam's needle, Spanish bayonet, yucca and needle palm, is a virtually stemless broadleaf evergreen shrub (though it looks more like a perennial than a shrub) that is native to beaches, sand dunes and fields from South Carolina south to Florida and Mississippi. It is surprisingly hardy to zone 4, and should survive our Edmonton winters with average protection.
