After 12 years since moving to our latest garden, this 5-foot plant has finally bloomed. It was already large when we arrived. It grows on a south-facing slope in Nanoose Bay, BC (possibly Zone 8b), and receives very little water. The people who lived here before us were not plant connoisseurs so I doubt it is particularly unusual. My guess is that it may be a Dracena but I'm not at all sure.
Cordyline australis. I see them around my neighbourhood, and we have one at my building, so you're right, not particularly unusual, but kind of exotic-looking.
Thank you very much Wendy. It's good to know the correct name which I can now add to my list of garden plants. It's not something I'd ever choose but it has earned it's keep, I think. If it ever got to be the size of the one in the photo, that would be pretty neat. Not in my lifetime.
