Trehane has been happy in my zone 3 rockery bed for ten years. It's still quite small though. Love the stunning blue/chartreuse combination.

This nice little Veronica is often mislabeled and sold as
"Veronica austriaca 'Trehane'

It is also certainly not to be confused with a totally different plant: Veronica montana 'Corinne Tremaine'

This is a very desirable plant. It makes a nice ground cover without being invasive. The blue flowers complement the yellow green foliage. Do add it to your wish list.
It does well in zone 4b.
