Thank you for your fast reply.

I'm glad you asked I really like the flowers thinking about doing the same thing in front of my house

How tall are these plants?

For reference the tan portion of that stucco wall behind is three feet tall. Those plants are fairly young in the picture and may double in height approximately.

What species is this purple sage salvia? I have googled it and there are tons of picture but none look like this. Thanks

Hi there, This is Salvia 'Indigo Spires'

Thank you so very much for the fast reply!

Beautiful blue, hope I can find them in the u.k
