Iris mystery

This morning I found a mystery waiting for me in my garden. This Iris ensata (Japanese Iris) was in bloom. The mystery? I know for sure I didn't plant it in this spot. It was right against the Belgium block of my driveway.

As I looked around, I remembered that in the past few years I've been lax in removing spent pods on some of my Iris. Could they have seeded?

Suddenly my eyes spied this small group of Iris ensata about to come into bloom. Ok, now I was sure that these weren't planted by me. Why would I plant an Iris in the middle of a daylily clump? Not only are these two plants conjoined at the base but I know I've never had a Japanese Iris growing in this spot before.

This is quite a surprise to me. Neither of these photos do justice to the colors in the garden. Even tweaking isn't getting me the color I'd like to see.

As the light conditions change through the day I'll try again to capture what is here. Apparently, there are some new Iris in my garden but I'm not complaining.

Has this ever happened to you?
