These are not trellising/climbing plants, although they do stand tall. Just leave them in the pots, in sun. They will not stay green; in fall they will die back. You can trim the dead foliage and leave them. Note, however, these are available as annual (Rudbeckia hirta) and perennial (Rudbeckia fulgida) varieties. If you have an annual, it will not come back. Check the plant tags.
