Foxglove (digitalis mertonensis). Also tiger lily (duh!), and although it's not dapped, catmint (nepeta).

I can think of one perfectly lovely speckled flower. Unfortunately, it comes with a perfectly ugly name:

Lungwort.

`Can't see calling a cat by that name.

By the way, a photo link is below.

There's really cute pink rose named "Freckles". Every time I see a picture I want it.

Happy Gardening!

Amazing. I have a tortie named Freckles. Didn't even know it was a flower.
