Anyone using combos in clematis that they would recommend? For example I've done Purpurea Elegance with Duchess of Albany for a very good effect. I'm curious about an accent for Huldine. Obviously the Clem would have to be vigorous to compete.
Huldine with Jackmanii.
Huldine with Rouge Cardinal or Hagley Hybrid which will highlight the mauve back stripe on Huldine.
Being in zone 4, I wouldn't grow Jackmanii - it can be disappointing in cold zones. If you like the white-purple combo, Polish Spirit would be a good choice as would Etoile Violette.
