Since I've been having a lot of questions about this, I thought I'd elaborate further. This project branched off from the original "Amazing Aberrants" project, which aimed to collect observations of unusual genetic mutations and aberrant. Albinos, odd colour forms that were atypical, or otherwise. The decision was eventually made to diverge "cristate" and "fasciate" plants into a new project as seen here.
Fasciation, sometimes called cresting or cristation, is when plant structures do not grow in a typical fashion, forming unusual structures of multiple merged stems, deformed flower clusters, or peculiar leaves. The common appearance is flowers or stems appearing "doubled up", with features almost literally blending together.
The intention is to track cases where this is just a random genetic mutation. However this may be caused visually by a number of more quantifiable reasons: diseases, arthropod galls, such as those caused by mites or wasps. Fungi such as those ...more ↓

However this may be caused visually by a number of more quantifiable reasons: diseases, arthropod galls, such as those caused by mites or wasps. Fungi such as those causing "witches broom". Bacteria and other infections. These are non-genetic examples and are not the focus of the project! I realize this reaches only a minority of folks since in many cases the cause is unknown. But if it is a known pathogen or gall species causing the result, it does not need to be included.
