F.W.I.W. I see that under British conditions anyway 'Crater Lake Blue' and 'Royal Blue' were apparently determined to be top performers in 1993 (A.G.M. = Award of Garden Merit):

Closer to home Chicago Botanic Garden also has an ongoing garden plant evaluation program of some scope. I found this on their web site (unfortunately it appears the only forms of this species they looked at were 'Crater Lake Blue' and a pale one):

Bart, can you grow veronicas in Italy? Have you tried some already? How did they do?

The only blue perennials I can grow are Aster x frikartii, Felicia amelliodes and Ceratostigmas.

hi Embothrium,

just wondering if you ever chose one of the veronicas and which one - im looking at Kapitan for melbourne australia and i just wonder how it went with you. I dont want one that runs too easily.
