Forget-me-not’s blue flower is familiar to most people, and as the name suggests the plant is a symbol of love and friendship. It has not always had such a pretty name however: in Sweden it has been known as devil’s eye, and goat’s eye, which was used in Finland, doesn’t sound a whole lot more attractive. Forget-me-nots have been popularly used in folk medicine to treat eye infections. This comes from the Doctrine of Signatures, a belief that the appearance of a plant provided clues to its medicinal properties – and forget-me-not’s corolla is like a blue eye with a pupil. The flower attracts pollinators that are guided by yellow protruberances in the centre of the flower towards its nectar.
Strict forget-me-not is one of Finland’s more noticeable forget-me-nots. It is one of the earliest-blooming small plants on rocky outcrops, and is able to flower, ripen its seeds and die before anyone has noticed. It favours dry habitats and is in a rush to reach the end of its life cycle before the hot days of summer arrive. Strict forget-me-not is, alongside early forget-me-not (M. ramosissima), the smallest of the dozen forget-me-nots that grow in Finland. The easiest way to distinguish them from each other is perhaps the length and position of the fruit-stalk: strict forget-me-not’s fruit stalks are clearly erect and shorter than the calyx, while early forget-me-not’s are around the same length as the calyx and spreading to the side.
