Heuffel's crocus

About

Heuffel's crocus, or Carpathian crocus, is the brightest sign of spring in the Carpathians. As soon as the snow melts, mountain meadows, hayfields, and forest edges are covered with solid purple carpets, where there can be 20–100 flowers per square meter. In folk tradition, they are called brandushkas, bryndushas, or maslyankas — for their shiny petals that seem oiled.

This spring ephemeral grows 10–19 cm tall from a small bulb. The leaves are narrow, linear, with a silvery stripe in the middle, and are short during flowering. The flower is solitary, with six purple, rarely white petals with a darker V-shaped spot near the tip; the stigma is yellow-orange, and there are three stamens.

The crocus blooms in March — April in the foothills, and higher in the mountains — in May and even June, following the snow line. The species' range includes the Eastern and Southern Carpathians and the Balkans. In Ukraine, the largest populations are found in the mountains, although the crocus also occurs in Prykarpattia.

Heuffel's crocus is listed in the Red Book of Ukraine with the status of 'not evaluated'. Therefore, picking bouquets and digging up bulbs is prohibited, even though the flowers seem abundant. It is also important to remember the poisonous lookalike: Colchicum autumnale resembles the crocus but blooms in autumn and has six stamens.

Where in the Carpathians

The map shows where naturalists recorded the species (GBIF, CC0 and CC BY records), not every place it lives. The Ukrainian Carpathians are less studied, so a blank area does not mean the species is absent.

When to see it

From naturalists’ observations in the Carpathians (iNaturalist, research grade): the darker the cell, the more often the species is seen that month.
