Solved Identification of shrub

Could someone please tell me the name of this shrub, I have forgotten it and the label is lost.
The shrub smells of thyme ? menthol ?

 

Is it prostanthera? One of the hybrids?
They're rather tender so great if yours is doing well!

Thank you all, yes it's Prostanthera, I remember it now I've seen the name.
It has died @CarolineL and I want another one so had to know its name .

 

That's a shame @Michael Hewett . I found only prostanthera cuneata to be reasonably hardy - poorinda ballerina and others need to be more protected.

 

Prostanthera ovalifolia.
We grew this in mild South Wales and it died.
It is a tender plant.

• H3: hardy in coastal and relatively mild parts of the UK (-5 to 1.)
• 
  
• Where as the other one Prostanthera cuneata is hardy even up here in Scotland.

I used to have P. cuneata too, and I put them in a shed every winter, but I think vine weevils got them both.
