A low creeping plant. It grows 5-8 cm high. It spreads 1-2 m wide. It spreads by runners. These produce roots at the nodes. The leaves are like ivy. They are round to kidney shaped and dark green. They are scalloped along the edge. The flowers are purple and white violets and on long stems. The fruit are egg shaped.
