Trillium kamtchaticum is from east Asia; Siberia, Korea, China and Japan. Likely it was first documented from the Kamtschatka Peninsula. One site calls it a Nipponese pixie, which might be less of a mouthful. This little delight can be seen at Longwood Gardens in Pennsylvania. There are seven or so species of Trillium in east Asia. All the rest are in the US or Canada.
