Baikeisou

Veratrum oxysepalum var. oxysepalum (Japanese name: Baikeisō) is native to East Asia, including Japan, and is a large perennial herb that grows in somewhat dense clusters in moist grasslands of low-mountain to subalpine zones.
It grows to a height of 1.5–2 m.
The leaves are elliptical, 20–30 cm long and up to 20 cm wide.
From July to August, it produces greenish-white flowers with a diameter of 1–3 cm. The stamens are significantly shorter than the perianth segments.
When young, it resembles Oobagiboushi (Urui) and wild garlic (Ainu negi), leading to many cases of food poisoning due to accidental ingestion. Flowers
