Spiderwort

I noticed something the other day that had never caught my eye before.  I have three different colors of spiderworts. Yet I have only ever planted one.

I think this is the original color.  It came from my brother years ago.

This one is a little less blue.

You can appreciate the difference a little better when they are next to each other.

Then there was this one that was much lighter, and some are double!

There is definitely some mutating  going on out there.
