Hypericum scouleri is a perennial herb that is native to California, and also found elsewhere in western North America.
[Wikipedia] Taxonomy: Hooker named the species scouleri to honor the naturalist John Scouler who accompanied David Douglas on his expedition to the Columbia river in the 1820s.[4] In English it is generally called Scouler's St. John's wort.[12] It is also called Western St. John's wort on occasion,[13] however this name is more commonly applied to Hypericum formosum.
