The annual herbaceous plant reaches a height of about 5 to 20 cm. The stem is usually rigidly upright and can be present individually, but also in groups. It is not very knotty and hairy. The leaves are elongated, blunt, the lower ones are usually arranged in rosettes and have short stems, the upper ones are sessile. The hairs on the nerves of the underside of the leaf have a hooked, curved tip.
The flowers are light blue and are in the very end very elongating, multi-flowered wraps . They have a diameter of about 1 to 1.5 mm. The flowering period is March to June.
The fruit stalks are rigid and upright and are at most half as long as the calyx. Even at the time of fruiting, the flower stalks are hardly more than 1 millimeter long. The lowest are usually provided with bracts .
The number of chromosomes is 2n = 36 or 48.

Location requirements
The sand forget-me-not grows in sunny sand lawns, on dunes, on rock heads, on paths or in sand fields. It prefers warm, dry, lean, more or less base-rich, mostly decalcified, moderately acidic sand and stone gravel soils. It is a shallow root (up to 15 cm). It is a character species of the Sedo-Scleranthetea class, but also occurs in gappy Festuco-Brometea societies or in societies of the Aperion Association.
General distribution
Myosotis stricta occurs in almost all of Europe. East to Siberia, the Caucasus and West Asia, it occurs from North Africa and the Azores through almost all of Europe to Iceland and northern Russia. But it is missing in Great Britain and Ireland. It is a Eurasian continental floral element. In Austria the species is rare, in Switzerland it is generally absent. In Switzerland, it even rises in the Saas Valley in Valais to 2178 meters above sea level.
Distribution in Germany
The sand forget-me-not is widespread in northern Germany, otherwise it is scattered to rare and can be found up to the montane level.
