growing up, we called these tiger lilies. which I loved as a girl, because it is a name from Peter Pan. the name of the lovely and strong princess who didn't need much saving (like Wendy did).
though am not sure it really is a tiger, it very definitely is a sign of summer in Kansas. as they grow everywhere.
I had transplanted these from my mom's farm last spring. And now, they bloom along my fence. And I wish I'd planted more.
