Spanish bluebells and ceanothus

The blue shrub in the Centre? Is it a Ceanothus?

Yes, yes.
I looked up "ceanothus" and I think you're right. Thanks for the ID :-)

I saw big ones in England and they grew as if they were proper trees, but mine is very very low and it won't wanna go vertically.

There are tall ones, evergreen ones, prostrate ones and variations of blue tones.

Thank you again, Siris (^^♪
