what kinds are perennials
I know the Hardy hibiscus, they die back to the ground each year and make new shoots in spring. But i'd like a more woody branching variety not with the saucer type flower but the smaller more formed ones. I bought some last year, not sure what they are and they were definately annuals as the woody part is now all just hollow tubes. unfortunately no seed pods ever formed on the flower stems as they all fell off after blooming. I grabbed hold of one by the base and it wont budge, so the roots are all still in place not rotting away, but it shows no sign of producing anything other then future composting material.
The hardys may be the only perennials , if not any suggestions are welcome and pictures appreciated.
