This little Thunbergia vine is not growing out of the pot but rather into it from below. It has wandered all over my front and back gardens, then dies back and has to be untangled from the rest of the plants. It is fun to see where it is going to wander off to next. It somehow got from the front yard to the back without my help and with no clear pathway, as the house is in-between and paved with a stone terrace all the way around it.. One of nature’s grand mysteries. This fast-growing little plant is also called clockvine or black-eyed-susan.
