Thanks Chelle, Lin and Ann, I think again Hebe 'Midsummer Beauty' must be the one, the likeness to too prominent..
I guess it is a cultivar of Hebe salicifolia, Lin, You're right about the relativity of info on the height! I have found one like that in my botany book and there it says hardy to zone 7!! Can grow to 3 m tall and more..!
