Mystery yellow "blue boy"

Can you help me to identify this plant? It is supposed to be a perennial and it was my aunt who gave me several of them in early spring, but just one survived. She told me, these plants are called "blue boys"... Obviously, I was expecting something with blue flowers, but it blooms now with yellow ones... I googled "blue boys", but found nothing related to flowers...

Although looking at mine the buds have a purple hue to them, also on the foliage.

Sure looks like the same flower.....

Some also call it an evening primrose.

Oenothera macrocarpa /Missouri evening primrose. Invasive in my Z6 CT garden altho' I didn't find any mention of that on the Missouri Botanical Garden website. If you don't like it, rip it out...it'll be back.

Here is a link that might be useful: Missouri Botanical Garden

Ken how long would you say?

I believe I've had mine for 3 years now.

If the flowers open during the day, they are likely Oenothera fruticosa "sundrops". A spreader but fairly easily removed if it overgrows its bounds.

If the flowers open at dusk, it could well be Oenothera biennis, common evening primrose, considered a noxious weed which should be removed immediately.

I find it very long lived (NW Illinois) and it is a great plant to intersperse all over the garden for a touch of yellow early in the spring. In my gardens I find that in early spring most everything is purple/blue, pink and white. The yellow adds a zing. It is so easy to take bits off of it and plant it all around. I love seeing it here and there in my hosta beds.
