About Trinity Buckwheat (Eriogonum alpinum) Eriogonum alpinum is a species of wild buckwheat known by the common name Trinity buckwheat. This rare plant is endemic to California, where it is known from only about ten occurrences in the vicinity of Mount Eddy near the border between Siskiyou and Trinity Counties. It is a state-listed endangered species because of its rarity. This is a perennial herb growing in mats no more than 15 centimeters wide and eight tall. The woolly greenish leaves are rounded and one to three centimeters long. The plant produces an erect inflorescence of bright yellow to pinkish flowers, each under a centimeter wide. The fruit is an achene about half a centimeter long.
