Gifted plant. I was given this plant as a gift and I think it's a penstamon? All it says on Tesco label is 'Summer flowering Perennial' No sign of actual name of plant on lable! Unbelievable! Any ideas which variety? Many thanks.

Might be Pensham Czar.

Seaburngirl-what a good idea! Wil email and see what comes back. The end of the stems are very droopy even when it has had a good soak.
steragram - thank you for that Id.

I used to have Czar but mine was a paler lilac than this one.

It matches mine.

Steragram -I think you're right. Although given with best intentions -the plant does not look happy and droops heavily even when watered and has a white wash of something over the top of plant. Have planted in garden but do not hold out much hope.:(

well it is a penstemon but there are so many like this for flower form that I wouldn't know where to start. I though I had id one of mine then in a gc today I saw 2 others that it could be.
why not email Tesco and ask them if they have lists of names or at least their supplier.
