About plant names...

Ground-ivy is not a North American native, but after its introduction from Europe and southwestern Asia, it has become widespread. It is a member of the mint family.

Identification: Ground-ivy has kidney-shaped leaves with scalloped edges, up to 1" (3 cm) in diameter, attached in opposing pairs to a stem that is roughly square in cross-section. Often only 3" (7.6 cm) tall, it sometimes reaches 12" (30 cm). Flowers are blue, purple, or lavender. The flower shape is unusual. A small upper petal is divided into two lobes. A larger lower petal has a lobe on either side, and a large bottom lobe that is divided into two more lobes. Each flower is only about ⅜" (9.5 mm) across. These plants commonly appear in lawns.
