Yep. Mine are dead too. Bought them last year in June as full grown plants in flower. Fab when planted out, but died after they'd finished flowering in October. No sign of growth this year, just a bunch of dead stems. Aklthough winter was a bit nippy here in the SE, most other stuff survived ok. So much for being hardy perennials then.
