TBM C (Rooted Plants)

"Melted Wax" Cactus: A Comprehensive Look at Trichocereus Bridgesii f. Monstrose 'Clone C' 

The world of cacti cultivation is rich with unique and fascinating specimens, among which the Trichocereus Bridgesii f. Monstrose 'Clone C', often referred to as "TBM C," stands out for its distinctive and unusual growth patterns. This particular cultivar is a member of the larger and highly variable group of Monstrose Trichocereus Bridgesii, a species native to the high-altitude regions of Bolivia. While other clones, such as the long-form 'Clone A' and the short-form 'Clone B' (famously known as the "Penis Cactus"), are more widely recognized, 'Clone C' offers a unique aesthetic that has captivated collectors.

The "Melted Wax" Morphology

The defining characteristic of TBM C is its "melted wax" or "semi-Monstrose" appearance. Unlike the more uniform and predictable growth of Clones A and B, Clone C exhibits a highly irregular and sculptural form. Stems may appear to droop or "melt" downwards, with unpredictable rib structures that can shift, terminate, or spiral along the plant's body. This creates a visually striking specimen where each plant is essentially a unique living sculpture. The epidermis is typically a bluish-green, characteristic of Trichocereus Bridgesii.

It is crucial to distinguish TBM C from "TBMC." While the nomenclature can be confusing, "TBMC" generally refers to the crested form of Trichocereus Bridgesii f. monstrose, which exhibits fan-like or brain-like growth. TBM C, on the other hand, maintains a columnar, albeit distorted, growth habit.

Origin and Nomenclature

The naming and popularization of the various TBM clones, including Clone C, are largely attributed to the ethnobotanical nursery Sacred Succulents. While the precise origin of Clone C—such as the specific parent plants or the exact circumstances of its selection from a batch of seedlings—is not definitively documented, it is understood to have been isolated for its unique "melted wax" traits. Like other TBM clones, it is propagated vegetatively through cuttings to ensure the preservation of its distinct genetic characteristics.

Cultivation and Care

The care for TBM C is broadly similar to that of other Trichocereus Bridgesii varieties, though its particular morphology warrants some specific considerations.

Soil: A well-draining soil mix is paramount. A mixture of potting soil, perlite, and coarse sand (e.g., in a 1:1:1 ratio) is a suitable starting point. Good drainage helps to prevent root rot, to which these cacti can be susceptible.

Light: TBM C thrives in bright, indirect light. While it can tolerate some direct sun, particularly in the morning, intense afternoon sun can cause scorching. When grown outdoors, partial shade is recommended.

Watering: Like most cacti, TBM C is drought-tolerant. Water thoroughly when the soil is completely dry during the growing season (spring and summer). Reduce watering significantly during the dormant period in fall and winter. Overwatering is a common cause of problems, including fungal infections.

Temperature: This cactus prefers warm temperatures during the growing season. It can tolerate mild frost for short periods if kept dry, but it is best to protect it from freezing conditions.

Pests and Diseases: TBM C is particularly prone to fungal infections, which can manifest as black or orange spots on the epidermis. Good air circulation and proper watering practices are the best preventative measures. Mealybugs and spider mites can also be occasional pests.

Comparison with Other TBM Clones

To fully appreciate the uniqueness of TBM C, it is helpful to compare it with the other commonly known clones:

TBM Clone A (Long Form): This clone is characterized by its long, relatively smooth, and often spineless segments. It tends to grow in a more upright and less clumping manner than Clone B.

TBM Clone B (Short Form / "Penis Cactus"): This is the most common and recognized form, featuring short, thick, and segmented growth that resembles a phallus. It is a prolific pupper, forming dense clusters.

TBM Clone C (Melted Wax): As detailed above, this clone is distinguished by its irregular, "melting" growth and unpredictable rib formation.

TBM Clone D: This is another, less common, semi-Monstrose clone that exhibits its own unique and variable growth patterns, often with more pronounced and lumpy tubercle formations than Clone C.

In conclusion, Trichocereus Bridgesii f. Monstrose 'Clone C' is a remarkable and sought-after cactus for enthusiasts who appreciate its bizarre and beautiful sculptural qualities. While its care requires attention to its susceptibility to fungal issues, its distinctive "melted wax" appearance makes it a worthy and fascinating addition to any collection of unusual succulents.
