Himalayan Blackberry (Rubus bifrons [R. aremeniacus, R. discolor, R. procerus]) on Aug 23, 2023
Submitter does not have a specimen
Description of specimen
Himalayan blackberry has gone by many names in the Pacific Northwest, and there is yet a common consensus on which species are here and what to call the most dominant species. However, control options are similar.
At the corner of Sw Lodestone Dr and Sw Opal Dr in Beaverton is an overgrown swamp. Now that it’s summer, the area is being overtaken with the invasive Himalayan blackberries. It’s growing in the water area and over the fences. This area is NOT being maintained by Beaverton.
For most of the year it stinks. As soon as it rains it smells like sewage and the area is filled with mosquitoes. Plus people have been tossing their trash into that area. And, it has big rats.
