Wild Celery (Heracleum lanatum), as known as cow parsnip or poochki, occurs in many regions of coastal Alaska, including Valdez.
"Wild Celery, also known as cow parsnip can be both useful and harmful. It has been used for sustenance as well as traditional remedies in cultures across its range. However the chemical furanocoumarins in its sap and outer hairs can cause irritaiton to the skin. If exposed to UV light after contact with skin, this chemical can cause a sunburn-like blister." - Valdez Parks & Recreation
