Crested Fasciatied Succulent - Echeveria elegans - 4” Pot Rare
Cresting is a mutation that occurs as the plant grows. Instead of producing more branches or stems, the plant flattens out and creates a wide flat surface. The leaves generally grow along the top of ridge of this wide growth and they are very compact.
Fasciation (pronounced /ˌfæʃiˈeɪʃən/, from the Latin root meaning "band" or "stripe"), also known as cresting, is a relatively rare condition of abnormal growth in vascular plants in which the apical meristem (growing tip), which normally is concentrated around a single point and produces approximately cylindrical tissue, instead becomes elongated perpendicularly to the direction of growth, thus, producing flattened, ribbon-like, crested (or "cristate"), or elaborately contorted tissue. Fasciation may also cause plant parts to increase in weight and volume in some instances. The phenomenon may occur in the stem, root, fruit, or flower head. Some plants are grown and prized aesthetically for their development of fasciation. Any occurrence of fasciation has several possible causes, including hormonal, genetic, bacterial, fungal, viral and environmental causes.
Fasciation can be caused by hormonal imbalances in the meristematic cells of plants, which are cells where growth can occur. Fasciation can also be caused by random genetic mutation. Bacterial and viral infections can also cause fasciation. The bacterial phytopathogen Rhodococcus fascians has been demonstrated as one cause of fasciation, such as in sweet pea (Lathyrus odoratus) plants, but many fasciated plants have tested negative for the bacteria in studies, hence bacterial infection is not an exclusive causation.
Additional environmental factors that can cause fasciation include 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. Some plants, such as peas and cockscomb Celosia, may inherit the trait.
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.
Although fasciation is rare overall, it has been observed in over 100 plant species, including members of the genera Acer, Aloe, Acanthosicyos, Cannabis, Celosia, Delphinium, Digitalis, Euphorbia, Forsythia, Glycine max (specifically, soybean plants), Primula, Prunus, Salix and many genera of the Cactaceae (cactus) family. Cresting results in undulating folds instead of the typical "arms" found on mature Saguaro cactus.
Echeveria elegans is a succulent evergreen perennial growing to 5–10 cm (2–4 in) tall by 50 cm (20 in) wide, with tight rosettes of pale green-blue fleshy leaves, bearing 25 cm (10 in) long slender pink stalks of pink flowers with yellow tips in winter and spring.
Echeveria elegans is cultivated as an ornamental plant for rock gardens planting, or as a potted plant. It thrives in subtropical climates, such as Southern California
As it does not tolerate temperatures below 7 °C (45 °F), in temperate regions it is grown under glass with heat. It has gained the Royal Horticultural Society's Award of Garden Merit.
