Thank you for your question. This looks like lesser celandine (Ranunculus ficaria), which is considered a "B" Rated Weed by the Oregon Department of Agriculture. Considering it appears that you will be managing it within a viticulture operation, I highly suggest contacting your local Yamhill County Extension Office and speaking to Heather Stoven (503-434-8910) or calling the Columbia County Extension Office and speaking to Chip Bubl (503-397-3462) for management guidance.
