| Info | Maybe the best of the mice so far, this white-edged sport of the all white and almost impossible to grow 'Solar Mouse' is very vigorous. 'Mouse Madness' emerges with very bright white margins in the spring that do not melt but stay attractive well into late summer. Rounded blue green leaves with wide white margins that become greenish white in the summer. |
