Contrary to appearances, lichen is organic and growing. But it grows slowly. Really slowly.

Lichen looks like flaking paint.
Inorganic? No, it ain’t.
Inorganic? No, it ain’t.
Do not try to watch it grow.
Each micron takes a day or so.
Nerdy 😉 Note
Dunno enough lichenology to say how slowly my lichen grows. From the wide range of known lichen growth rates and my very casual observations, I could go with either “hour” or “day” as a crude monosyllabic estimate of long my lichen takes to grow a millionth of a meter wider. Compared to watching lichens grow, watching grass grow would be like watching hockey.
