Haberlea rhodopensis

Haberlea is a monotypic genus of flowering plants in the family Gesneriaceae. The only member of this genus, Haberlea rhodopensis, is endemic to parts of Bulgaria and a small part of northern Greece, especially in the Rhodope Mountains. Common names include Orpheus flower and resurrection plant because of the remarkable ability of Haberlea to survive very long periods of desiccation. The species is a stemless, evergreen perennial found in north-facing rocky habitats. Basal rosettes of dark green leaves bear trumpet-shaped flowers in shades of white, violet or purple in spring and summer. Despite the zygomorphic nectar-producing flowers (which are considered an ancestral character) and the overall trend in Gesneriaceae, Haberlea rhodopensis is only rarely pollinated by bees and does not have specific pollinators. Its evolution has switched in the direction of providing pollen as a reward and generalisation of pollinating insects, a trend that is observed in the only other European genus......read more on Wikipedia.
