Vegetative characteristics

The alpine forget-me-not is a perennial herbaceous plant that reaches heights of 10 to 15 centimeters. The basal leaves are in rosettes.

Generative characteristics

Flowering time is mainly June to August. The flowers are up to 9 mm wide and light to intense blue with yellow throat scales.

The number of chromosomes is 2n = 24 or 48, less often 20, 70 or 72.

Possible confusion

The alpine forget-me-not is often confused with the Himmelsherold , which has roughly the same flowering period. Difference: The Himmelsherold only occurs from altitudes of 2000 meters and has numerous very small leaf rosettes that give a cushion-shaped impression.

ecology

The short corolla tube also allows short-nosed insects access to the nectar . Pollinators are two-winged birds , bees and butterflies .

The flowers are lilac when they open, later sky blue. This color change is typical of the predatory family . This is due to the fact that the flower pigment anthocyanin reacts like litmus : in the initially acidic cell sap it turns the flowers reddish, in the later alkaline cell sap it turns blue.

Occurrence

Myosotis alpestris thrives in the mountains of Europe, Turkey, Armenia and Georgia.

Frequent locations for Myosotis alpestris are damp areas, lawns, rubble or block corridors at altitudes of 1300 to 3000 meters. The alpine forget-me-not grows on both silicate and calcareous soils . In Central Europe, it thrives primarily in plant communities of the order Seslerietalia albicantis, but also occurs in communities of the classes Salicetea herbaceae or Thlaspietea rotundifolii and the associations Adenostylion or Rumicion alpini.

From Myosotis alpestris numerous garden forms have emerged that very easily become feral.

Systematics

Myosotis alpestris was first published by Franz Willibald Schmidt .

From Myosotis alpestris subspecies have been described (selection):

  • Myosotis alpestris F.W. Schmidt subsp. alpestris
  • Myosotis alpestris subsp. pyrenaeorum (Blaise & Kerguélen) Valdés : It occurs in Spain and France.
