Image of Primula halleri J. F. Gmelin

Description:

Slo.: dolgocvetni jegli - syn.: Primula longiflora All. - Habitat: Stony alpine grassland, calcareous ground probably somewhat acid; sunny, open, wind and rain exposed place, average precipitations ~ 3.000 mm/year, average temperature 0-2 deg C, elevation 1.940 m (6.450 feet), alpine phytogeographical region. - Substratum: humus soil. - Comment: Primula halleri is one of the rarest among 14 species of this beautiful genus growing in Slovenia. Also in other Alpine countries it is nowhere common and in some them is protected by law. Primula halleri is especially tender and fragile due to its flowers having unusually long and thin corolla tube. The plants were growing in a group of several on a relatively small area. - Ref.: (1) D. Aeschimann, K. Lauber, D.M. Moser, J.P. Theurillat, Flora Alpina, Vol. 1, Haupt (2004), p 634. (2) A.
