Blue elderberry

Blue Elderberry, Mexican Elderberry, or Tapiro is a deciduous shrub or small tree, growing up to as tall as 30 feet. It is native from Oregon to Baja all the way to western Texas. It has cream or yellow flowers in the spring and purple berries in the fall. Its berries are one of the most important source of food for birds in California. Blue Elderberry is tough, easy to grow, and grows very rapidly. It can grow from a 1 gallon container to a 15 foot tree in 3 years if happy. It handles a variety of different soil moisture levels once established. It can handle permanently moist soil near stream sides or seeps, and will thrive next to or in regularly irrigated areas. Once established, it also grows well in fairly dry soils, though in drier conditions it will normally go deciduous or semi-deciduous in the summer and fall, and green up in the early winter. Drought-stressed Blue Elderberry’s often end up more attractive than ones that get plenty of year round water, frequently developing interesting gnarled branches and thicker though shorter trunks over time. It likes part shade or sun, and will tolerate full shade, though in full shade it will look rangy as its branches search out for more sun. Description from calscape.org
