The mouse-ear tickseed (Coreopsis auriculata) is native to the southeastern United States, where it is found in open woodland and pine barrens.
It blooms earlier than other species of tickseed, and is usually covered in orange-yellow flowers by late spring.
‘Nana’ is a low-growing cultivar and makes a handsome ground cover, as can be seen in the Wild Garden now.
Members of the genus Coreopsis are commonly called “tickseeds” for the rather obvious reason that the seeds could indeed be mistaken for small, black ticks. The mouse-ear part of the common name refers to the small lobes at the base of each leaf, which look a little like the ears of a mouse.
