Hi there,

I wanted to let you know that I am working on this. I don't recognize it right away, but it looks familiar. I don't have any of the handy plant apps, but I hope to have an answer for you soon. (-:

My apologies for the delay. My source, our Extension Agent, Ed Brown, was tied up with the county fair last week.

According to Ed:

"This looks like it might be the Woad plant, a biennial that produces a yellow flower during its second year. It was used as an indigo dye for many centuries. There are other options, one is a goldenrod with bunch gall midge (an insect infestation) or an American burnweed but the leaves don’t look right."

Here is a website with some information about the Woad plant:

If you know someone with an app for identifying plants, you might send them a photo. The apps can be surprisingly accurate, although not 100%. I am going to reassign your question, as someone else might have a different idea for you.

Keep gardening!
