Another mystifying plant!

Hi Again,

This is the other one (of many) that I am not sure about, although I am sure one of you knowledgeable people will be able to advise.

Hi Tony, The flowers are from another plant which is really pretty. But this one I don't even know if it flowers.

Thanks

don't think so, my penstemons are not upright like that, they tend to loll all over the place 

Could be a type of perennial lobelia
