I purchased this blue flowering plant from an Amish farm about 20 years ago. I cut it back each winter with no watering, bring it out in the spring, and it comes back to life each year. When I purchased it, they called it Blue Nancy.
Re: Blue Trumpet-shaped Mystery Flower Surely a gesneriad. Looks like some type of Achimenes, probably one of the nice hybrids.
Re: Blue Trumpet-shaped Mystery Flower Dang! Took too long looking up images and Ron clicked submit while I still had the text box open. Man, he is always on the spot. Here is a link on Achimenes and relatives. http://www.gesneriads.ca/genach.htm
Nellie, I merged your two threads here. I think it is less confusing for readers if we keep the conversation in one place. Achimenes were more commonly grown in the past--it is an old time favourite. They are more popular in Europe than America. People should try this plant. That said, I have never grown it--I guess it will go on my list to order.
