Last summer I took a Penstemon cutting and it grew on well. I repotted it this spring in a large pot and it has continued to grow healthily but not a hint of flower buds yet. Any suggestions?

I find mine do not usually flower for 2 summers, I think it will flower for you next year if it looks healthy.
