Registered by Dr. Dick and Jane Ward of Ohio in 2013, this miniature size (4 inches high by 11 inches wide) cultivar is a sport of H. ‘Funny Mouse’. It has pale yellow foliage that is lightly wavy, broadly ovate and dull on top. Bell shape flowers bloom from June into July on scapes 6 to 8 inches tall.

According to the registration materials: "...golden yellow leafed "Mouse"..."

"H. ‘Solar Mouse’ (2013) – This was registered as having parentage of a sport of an unregistered sport of H. 'Blue Mouse Ears'. After much debate, and in the interests of providing as much information as possible regarding parentage, it was determined that the actual name of the parent from which the cultivar was derived, albeit unregistered, would be more accurate and thus, the parentage has been changed to a sport of H. ‘Funny Mouse’."
