I know I can also post in the id forum but i thought i would start with all you fellow canucks. Now i know i planted this thing about 3 years ago. Whatever it is was kinda dormant for a year, then last year just sort of looked like a broad leaf yucca or something but i don't recall having planted a yucca. This year it started sending up this spike about mid may and it grew and grew and grew (taller than me) and finally today one of the flowers opened.
