This A. pajaroense ‘Warren Roberts’ is planted on the bank next to the ramp going to Riverplace Marina on the Willamette. Next to it, by the vented green ‘box’, was an Arbutus menziesii that was established and doing well, untill the irrigation system was inadvertantly turned on. It collapsed quickly. This Manzanita and others nearby, including A. ‘Sunset’, hardly seemed to notice. I wouldn’t recommend the practice. Two Arbutus arizonica also perished.
