The Surprise Lilies came from the one-armed man

I was out in my front yard when a cool old guy with just the one arm came up to me and told me he had given some of the previous owners of our home a plant that gets real big, then dies... and surprises you later with flowers.
I said "They are Surprise Lilies" and he looked at me like I was an idiot. Apparently those Lilies have been there for ages.
Where's the surprise in that?

Then I saw him again yesterday standing in the alley on the side of my house grinning a big ol' grin. He was looking at my freshman-year back garden and the look on his face was like the garden just told him a really good dirty joke.

Then I thought about Twin Peaks. 'Cuz it seemed like a Twin Peaks moment.
