Veronica salicifolia 2 bushes (Saltaire BD18)

I have 2 self-sown plants of what I have always thought was a hebe, but the internet tells me is Veronica salicifolia. Evergreen shrub, to approx 2 metres, bearing spikes of white flowers now. One approx 50 cm in a plastic pot. One approx 80 cm in terracotta. To collect from BD18 please.
