I don't know what your zone is, but I'm zone 6a and I prune a Salvia greggii no later than late Summer and wait until late Spring the following year to insure hardiness of the Salvia. Sometimes a Salvia greggii will survive our Winters.
Welcome to ATP and if you're interested, come on over to the Agastaches and Salvias forum here at ATP!

I'm not familiar with Salvia greggii 'Strawberry'. I'll have to do a search for that one. Sounds like a beauty!
