Blue Forget-Me-Not

The Blue Forget Me Not (Myosotis stricta) is a species in the genus Myosotis. It is currently classified as Near Threatened on the IUCN Red List. Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate grasslands and steppes, and flooded grasslands and savannas, among 4 distinct biome types within the Neotropic biogeographic realm.

Cobble Forget-me-not

Cobble forget-me-not (Myosotis schistosa) is a small annual or biennial herb in the family Boraginaceae, native to riverine and coastal habitats in parts of Europe, particularly associated with slate, shale, or schist substrates and disturbed gravelly or rocky ground. Like other Myosotis species, it bears the typical small, five-petalled blue flowers with a yellow eye that give forget-me-nots their widespread recognition. The genus Myosotis encompasses dozens of species distributed across Europe, Asia, North America, and the Southern Hemisphere, many of which are adapted to specific, often nutrient-poor or geologically specialised substrates. Cobble forget-me-not is assessed as Data Deficient by the IUCN, reflecting limited information on its distribution, population size, and ecology. Botanical surveys in appropriate habitats across its inferred range—particularly slate-rich riverbanks and coastal cobble in Europe—are needed to clarify its taxonomy, distribution, and conservation requirements. Like many small annual herbs in disturbed habitats, it may be locally common in suitable microsites but easily overlooked due to its small size and annual habit.
