I'm thinking mullein. Does it look like this?

oenothera biennis would be my guess. Common yellow primrose, not a primula.

When I clicked on this post, I was thinkin "I wonder if its the same "wildflower" I have in a pot in my yard". And it was! Unfortunately I cant help ID it, but would also love to know what it is. Mine came from a wildflower mix from Wal Mart that I used as one of my wedding favors.

It's some species of an Evening Primrose, maybe a Oenothera grandis? Go outside one evening with a flashlight, you may see a sphinx moth fluttering around the flowers. The flowers are a great nectar source for night flying moths.

Oh, forgot to mention. It's not a weed by my standards. It's a native plant to your area.

Token has it right, common names are evening primrose and nine o clocks. You can watch these flowers open, right before your eyes, as they open very quickly & sometimes they will even shake a bit-we always watched them as children & I still enjoy doing so. They get lanky & weedy looking but I always let some reseed to watch open & show others. Look for the fattest bud in the early evening, then check about dusk & you will soon have their schedule. Mine opened about 8:45 pm last night. The blooms close during the day but will linger if it is overcast or rainy.

Yep. I'm with token, too. Nice scent also.

I'm getting better!

I collected seed of this last year and threw them out this spring. Nothing germinated. I'll be getting more seed from down the street this summer. I really want this in my garden. It's a great plant for tall borders.

Evening primroses are wonderful conversation starters. Before we moved to the new place, we had Summer Solstice parties in the 3rd weekend of June. The evening primroses were always blooming then. People would gather together to watch the buds quiver and shiver, then pop open. Fascinating!

Thank you, folks! It is a nice plant, and I only paid $1.00 for it.

It's blooming like crazy now!
