A common spring flower native to continental Europe and adjacent areas of Russia, H. nobilis often flowers in February or March, even before the ground is free of snow. It prefers richer soils, often overlaying calcareous bedrock and is usually found in deciduous or mixed conifer forests. Pollinators visiting the flowers are winged as well as non-winged (ants). The seeds have an elaiosome and are dispersed by ants (myrmecochory).

The UV impression of H. hepatica is almost similar to the visible one, except for the styles and pistils all are UV dark. The petals (honey leaves) reflect quite strongly in UV. Patches of conical cells contribute to this brightness.

 

Albino forms of H. nobilis are not uncommon. In UV, they appear similar to the normal coloured flowers (Rørslett unpubl.).
