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.
