What do these mean?



White alder is widespread in California and beyond, growing as a vase-shaped tree in moist settings. In Santa Clara County the white alder has slowly re-populated the valley along perennial waterways. The oval leaves and silver bark are reminders that white alder is a member of the birch family. Young trees grow quite rapidly with adequate water. It accepts a variety of soil types and sun exposures. Plant white alder where space and moisture allow, preferably away from drains and pipes that may be disrupted by the water-seeking roots.
