K northiae survived minus 15C or colder for me and flowered, In my
experience K hirsuta sulks if it does not get a  hot dry spot. It was also
hardy in the recent cold winters. K caulescens died. K uvaria hardy for me
too. I have a plant labelled K thomsoni which was also unscathed. Various
hybrids, sown as species, such as citrina and baurii were hardy, pauciflora
is definately not hardy in cold winters. K typhoides was hardy for many
years but I am not sure if I still have it.
 All in Derbyshire, England
