What is Veronicastrum japonicum

Veronicastrum japonicum or Kugaisou (scientific name: Veronicastrum japonicum) is native to Japan, China and the Korean Peninsula and is a perennial of the genus Psyllidae. In Japan, I grow naturally in the sunny field of Honshu. In the summer, I will put flower stalks out and extend flower inflorescence from the tip and add flower that gathered purple florets. The name of the flower was attached because the leaflets produced 4 to 8 pieces of wheat and many layers. The flower diameter of the small flower is about 0.5 cm and two stamens protrude. Young buds are edible.
