Bingo! It is definitely Penstemon. I had hit a dead end with this one, so I am grateful for everyone's help. Who knows; maybe someday I can answer a question or two. Cheers, Doug

Oh, and Selaginella isn't really a climbing plant, it's more of a spreading plant. It's good for hanging baskets and mixed planters - likes moist shade. I've used it sparingly in terrariums, but it can spread quite rapidly so needs some maintenance.

Thanks for the feedback. After checking other photos and details for the plant I am sure you nailed it. In Michigan it is actually considered a Noxious weed and quite toxic to livestock, especially horses; in Europe it is considered an ornamental plant good for landscaping purposes so I guess I will still include it in my collection of wildflowers even though most people in Mich. might disagree.
