The place on the map, a freeway exit, is precise because I was making an urban walk through the former course of Temescal Creek in Oakland. I'm no botanist, but blue elderberry would be a native plant for the area. Culverted spaces exist just to the west, that retain the creek's former course and some native flora. Please, if anybody can verify this, it would be exciting, since most of the corridor's native look had been destroyed in the 1960s when the freeway and it's entrances/exits were built.
Along Alpine Road. Most are now in bloom
Sambucus nigra is a species of elder native to most of Europe, northwest Africa and southwest Asia. It is most commonly called just Elder or Elderberry, but also Black Elder, European Elder, European Elderberry, European Black Elderberry, Common Elder, or Elder Bush when distinction from other species of Sambucus is needed. It grows in a variety of conditions including both wet and dry fertile soils, primarily in sunny locations.
