Do these pictures of the same plant help? (I'm new at this!) This is what the plant looked like when it first arrived. And then greened up some, and finally got the little 'flowers' on top.

Looks like heliotrope except it looks bigger than any heliotrope I've ever grown.

The flowers look to be still in bud? If so, post another photo when they open.

I think I can see white flowers peeping from those buds, look at Heliotropium arborescens ‘Alba’ ..

I will look those sites up and I will send later pics

I sure think you two are 'spot on' as they say!
I sure hope that's what it turns out to be.
