Growing in Southern Utah.
Maybe a bush with little purple blooms.

What is it and will it grow in Oklahoma?

Looks like Giant Flowered Purple Sage (Salvia pachyphylla) after the flowers fall off. Its flowers are actually blue, but they are surrounded by bright purple bracts. The bracts last much longer than the flowers.

If that's what it is, it grows well in Nebraska. Should be fine in Oklahoma, long stretches of humid weather might be the only concern.

It's not Salvia pachyphylla but looks like a Leucophyllum.
One species possibility Texas Sage (Leucophyllum frutescens)

I'm with Danita.

Thanks all!
There's no cold hardiness listed, I don't see anyone growing it in my zone.
Will it survive here?

It says here zones 8 and up http://aggie-horticulture.tamu...
I love that plant
