This little plant was given to me last year. It has lived in a brittle broken pot all winter and got put in the full sun this spring, yet it persists. It spreads readily, but is easy to pull up.

Anyone know what it is? The lady who gave it to me said it was a clematis, but that info was passed through a friend so it may not be exactly what she said.

The flowers are trumpet shaped. Any help is much appreciated. Thanks.
