The Olympic Peninsula hosts a diverse number of plants, including many edible plants. But unfortunately, poisonous plants, both native and introduced, also grow on the Peninsula. These poisonous plants run the spectrum from causing skin rashes when touched all the way up to potentially killing humans and pets if consumed. But with a little bit of knowledge and a good eye, you can identify these plants and protect yourself, your family, friends and pets from their harmful effects. Join Christina St John for the Green Thumb Education Series presentation “Poisonous Plants of the Olympic Peninsula” on May 25th.

Learn common poisonous plants found on the Olympic Peninsula, how to identify them and hear tips on how to safely remove them from your landscape if necessary. We will also compare them with non-poisonous plants that look similar. There will be samples available to look at for some of these poisonous plants.

Christina is the coordinator for the Clallam County Noxious Weed Control Program, which works with private and public landowners to ensure the control of noxious weeds within the county and is responsible for treating noxious weeds on county-owned land. Previously she worked at Shore Road Nursery and the Matt Albright Native Plant Center growing native plants of the Olympic Peninsula. She has also worked on restoration projects in California and North Carolina. Christina obtained her Bachelor’s degree in Ecology and Evolutionary Biology from UC Santa Cruz and her Master’s in Sustainable Forest Management at Oregon State University.
