This tough, versatile plant requires little maintenance. 'Georgia Blue' is willing to grow in sunny or shady spots, puts up with excessive rain or drought conditions, and attracts butterflies with a low blanket of sky blue flowers from spring into summer. Small, dark green leaves turn glossy burgundy in winter. Use it in containers or rock walls, or as a companion groundcover to spring bulbs under trees.
