A naturalized plant that blooms with white or light purple flowers about 3 mm in size.
The leaves are arranged in whorls at intervals of a few centimeters, with about 5 to 7 leaves. The surface of the leaves is covered with small hairs.
It grows on the ground in wastelands and on roadsides, creeping along the ground, and blooms from spring to summer.
The color of the flowers ranges from whitish to light purple.
I photographed it blooming next to a concrete block in early summer. The light purple flowers stand out, but the size of the flowers themselves is very small.
