Bernice Bjornson had this this to say about wild hyacinth in 1946:

“Brodiaea Douglasii (now Triteleia grandiflora) is a blue, paper-like flower. Each plant has two leaves which by the time the flowers open are drying or have dried so that the plant is often mistaken for a leafless one. The flowers are three to many in number and are all clustered at the top of the stem with all the flower stalks arising from the tip (a flower cluster called “umbel”).  The Indians considered the wild hyacinth as a gift of the gods to be eaten.  Brodiaea Douglasii is named after two men: James Brodie of Scotland and David Douglas, English plant explorer.”
