features

The elven crocus is a perennial herbaceous plant that reaches heights of 7 to 17 centimeters. This geophyte forms tubers as persistent organs. The basal leaves are parallel-veined; they have the white median strip that almost all species of the genus have.

The hermaphrodite, threefold flower is fused into a long tube in the lower part; it has a diameter of 2 to 3 millimeters. The six bracts are identical. The perigone are 25 to 45 millimeters long, 8 to 20 millimeters wide, monochrome (pale) violet to purple, the outside is often lighter, and they are not striped. The throat is white and hairy. Crocus tommasinianus f. albus is completely white.

The flowering period extends from February to March. The elven crocus is one of the earliest species of crocus to flower.

The number of chromosomes is 2n = 16.

Occurrence

The elven crocus occurs in southern Hungary, Croatia, Bosnia, Serbia and Bulgaria in fresh, deciduous deciduous forests and shady rock banks at altitudes of (300) 1000 to 1500 meters. This species is mostly found on lime. In Western and Central Europe it was naturalized as a stinzen plant .

use

The elven crocus is widely used as an ornamental plant in groups of trees, borders, parks and rock gardens. The species has been in culture since 1847 at the latest. There are some varieties with different flower colors, for example purple, lavender with white tips or white.
