I have a lovely black eyed Susan which has grown beautifully during the summer and I don't want to lose it. It grows on a trellis outside my house on a front wall. Shall I cover for the winter and, if so, with what? Regards, Anita.

It sounds like you have a black eyed Susan vine, since it is growing on a trellis:
This plant is not winter hardy at all, so you will need to bring the plant indoors for the winter. If this is not possible, you can take one or a few cuttings from the vine and grow them indoors, as described in the article.
