Pretty Pokeweed: Fall Color That Will Knock You on Your Butt

"Fall Color" isn't just limited to the changing hues of the leaves of deciduous trees this time of year. There are lots of colorful shrubs right now, producing flowers and berries, many of which are outstanding garden plants: cotoneaster, toyon, bottlebrush, the strawberry tree, Oregon grape, pyracantha and beautyberry, for example. But there are some pretty poisonous plants putting on a show right now in Northern California. Plants, that if you get a little too curious, could knock you on your ass.

For example, Laura writes in, with pictures:


This gorgeous invasive plant invading her Citrus Heights backyard? Pokeweed.

 After posting these pictures at the Get Growing with Farmer Fred Facebook Page, valley and foothill gardeners responded with words of warning:

"It is poisonous and it is becoming an invasive weed in California and so is posted as a noxious weed. I had a friend who had them in their yard and their son wrongfully thought they were elderberries so they had picked a bunch to make jam. Thankfully she didn't get time to make that jam and they got moldy."

"Definitely pokeweed...would not recommend putting in the compost pile...they also have a deep tap root and are hard to get rid of...Placer County posted a warning on this plant as being both poisonous and invasive."

Cindy Fake of the Placer County Cooperative Extension office has written extensively about the dangers of pokeweed (Phytolacca americana, also known as pokeberry, inkberry and American pokeweed):

"If you have seen this plant, beware!  Pokeweed, a poisonous invasive species, has become more and more common...pokeweed is a rapidly growing perennial shrub, up to 10 feet tall, with large leaves and red stems. While some homeowners may be tempted to keep pokeweed in their gardens because of the pretty white flowers and glossy dark purple berries, all parts of the plant are toxic to humans, pets, and other mammals.  Pokeweed berries provide food for birds, which are not affected by the toxins. However, the birds then spread the seeds, helping the plant to invade orchards, fields and yards, and competing with crops and ornamentals. Once established, pokeweed can be very difficult to eradicate.  It grows a very large taproot, and can have multiple stalks growing from a single root. Do not put plants or berries in green waste disposal bins or in compost. Unfortunately, the taproot usually remains and often resprouts the following year."

Those of you from the South may recall "poke salad" as more than a song by Tony Joe White. As Cindy Fake points out: "in some parts of the US, young pokeweed leaves are eaten after extensive processing to remove toxins, but even after processing, some toxins remain, so consumption is not recommended."
Agreeing with that is the California Poison Control System, which reports pokeweed (Inkberry) as a Class 3 toxin: "Ingestion of these plants is expected to cause nausea, vomiting, diarrhea and other symptoms that may cause illness but is not life-threatening."

• Do NOT induce vomiting.
• Remove any plant parts from the mouth or hands.
• Wash around the mouth and hands and give a few sips of water.
• Check for any irritation of the skin, mouth or tongue.
• Call the California Poison Control System at 1-800-222-1222

  1. "Extensive processing" ??? If by that it is meant you steam the heck out of the young leaves, then sure. But maybe my family (I grew up in NW Alabama) developed a tolerance for the toxins, as this was a daily dish in Spring. We never ate the berries, of course, but did use them to dye doll clothes .. and each other.

    It was quite a surprise to see it growing near Soil Born this Spring. I was wondering if it was a just fluke, or invasive. Now I know.
