Fasciation in succulents

Echeveria wuth Fasciation 

from the Latin root meaning "band" or "stripe"), also known as cresting, is a relatively rare condition of abnormal growth in plants in which the growing tip becomes elongated perpendicularly to the direction of growth, thus, producing flattened, ribbon-like, crested (or "cristate"), or elaborately contorted tissue. 

Some plants are grown and prized aesthetically for their development of fasciation.

Fasciation can be caused by fungi, mite or insect attack and exposure to chemicals. General damage to a plant's growing tip and exposure to cold and frost can also cause fasciation.

Fasciation is not contagious, but bacteria that cause fasciation can be spread from infected plants to others from contact with wounds on infected plants and from water that carries the bacteria to other plants.
we love Fasciation and actively propagate the effect by splitting into cuttings they also sell well ..
