Im almost sure by the glossy leave that it must be a Hebe spiecie
Think that it looks very like a Hebe macrocarpa but thats a tender one in the UK, NL, and Belgie. A hebe that is hardy to –5°C can grow to a big size more than 6.5ft (2 m) The one in your picture is probably closely related to Hebe macrocarpa.
