Galanthophiles will have spotted that the snowdrops are out.
The ones near me are showing a strong preference for pointing south.
The direction flowers point is influenced by many things, but a key consideration is whether the species is pollinated by insects.
Flowers that depend upon insects need to be highly visible and so they tend to orient towards the light and this is what makes them useful for natural navigation.
Snowdrops (Galanthus nivalis) are pollinated by bees and tend to orientate towards south.
They also spread by bulb division.
Plants that spread by bulb division do not move far or fast, which is why these plants are often indicators of civilisation nearby. In the case of snowdrops, you are probably very close to a garden or churchyard.
