What is Veronica laxa

Veronica laxa or hiyokusou (scientific name: Veronica laxa) is a perennial herb native to Japan, China, India, and Pakistan, belonging to the family Plantaginaceae. It grows wild in sunny locations in grasslands and forest margins in mountainous areas from Hokkaido to Honshu, Shikoku, and Kyushu in Japan. The grass is 50 to 80 cm tall, with several thin stems erect from rhizomes. The entire grass, especially the stems and sepals, are densely covered with white hairs. From June to July, a pair of narrow inflorescences 5-20 cm long are produced obliquely from the upper leaf axils, bearing sparse clusters of small pale blue-purple to pale red-purple flowers about 0.8 cm in diameter.
