Land Plants - invasive

Purple Loosestrife (Lythrum salicaria) on Aug 28, 2009

Submitter does not have a specimen
EDRR Status: Population treated

Description of specimen

I have attached a picture. These plants are very lanky because they are growing in so much underbrush. The plants have flower and unripe seedheads.

Let me know if it is okay to go back and cut the seedheads off. I have not contacted the City of Fairview, Multnomah County, Oregon about these plants.

Last year I found one plant on the northwest side of the same pond. Some folks from the local water/soil conservation office removed the plant. I lost the name of my contact there so I am hoping you can contact them for me to have the plants removed.

I tried to add an image. The plant is difficult to describe. Tall, floppy-because of the shade. I've reported this plant before, I used to grow it in my garden.

I have pictures but could not attach them.

PS the font used for the "two words" is difficult to read because the letters/numbers run together.

It is definitely ok to go back and cut the seed heads off. Please bag them and throw them in the trash. We dug up the patch you reported last year and then the carefully applied herbicide to the few leaves that grew back this year. We have been meaning to do a more thorough survey of the area and may get to it next week. It would be great to meet you out there to show us the plant so we could dig it up. Please give me a call at 503-539-5764 to talk about this.
Thank you so much for reporting.
