Cactus Kate '94 (Rooted Plants)

1994 Cactus Kate "PC", Acquired from actual stand at Cactus Kate's property in Watsonville CA in 1994 by a family member prior to Kate passing and Verne getting the cactus.

''Cactus Kate Pachanoi' is a specific cultivar of the San Pedro cactus, which is scientifically known as Trichocereus Pachanoi or Echinopsis Pachanoi. Here's what's known about it:

Origin and History:

The cultivar 'Cactus Kate Pachanoi' is named after "Cactus Kate," who, along with Jay Jackson, ran a nursery called Desert Theatre in Watsonville, California.

After Cactus Kate's death in 2003, some of her collection of Peruvian columnar cacti were "rescued" and moved, contributing to the spread of this cultivar.

It's important to note that some sources, like Verne, who reportedly "rescued" plants from Kate's nursery, maintained that his 'Cactus Kate Pachanoi' was distinct from the common "PC" (Predominant Cultivar) Trichocereus, even if they appeared indistinguishable to others.

General Characteristics of Trichocereus Pachanoi (San Pedro Cactus) and How 'Cactus Kate' fits in:

Growth Habit: Trichocereus Pachanoi is a fast-growing, columnar cactus that can reach impressive heights of 10-20 feet (3-6 meters), with some wild specimens reaching up to 40 feet (12.2 meters). It typically branches from the base, forming multiple stems.

Stems: The stems are usually light to dark green, sometimes glaucous (bluish-green) when young, and generally 6-15 cm (2.4-5.9 inches) in diameter. They typically have 6-8 ribs, which are broad at the base and rounded.

Spines: Spines are highly variable in T. Pachanoi. They can be few (3 to 7), unequal, and dark yellow to light brown, up to 1-2 cm long. Many forms, including 'Cactus Kate', can appear almost spineless or have very short spines.

Flowers: San Pedro cacti produce very large, fragrant, white flowers that open at night and can remain open into the following day. These flowers are showy, around 19-24 cm (7.5-9.4 inches) long, and are produced at the end of the stems. The flower tubes and fruits are covered with scales and black curled hairs.

Fruit: Oblong, dark-green fruits, 5-6 cm long and 3 cm in diameter, develop after successful pollination.

Hardiness: Trichocereus Pachanoi is surprisingly cold-tolerant for a cactus, hardy in USDA zones 8b-10, meaning it can withstand temperatures down to around 20°F (-9°C). This is due to its natural habitat in the high-altitude Andes Mountains.

Cultivation:

Sunlight: San Pedro cacti thrive in full sun but can tolerate partial shade, especially in hotter climates. If grown indoors, a south or west-facing window is ideal.

Soil: They require well-draining soil. A good cactus or succulent mix, often amended with pumice or perlite for extra drainage, is recommended. Good drainage is crucial to prevent root rot.

Watering: During the growing season (spring and summer), water regularly using a "soak and dry" method, allowing the soil to dry out completely between watering's. In fall and winter, during their dormant period, reduce watering significantly or cease altogether.

Fertilizing: Fertilize once a month during the growing season with a low-nitrogen cactus fertilizer or a balanced (e.g., 10-10-10) fertilizer diluted to half strength.

Temperature: They prefer warm, sunny environments. While cold-tolerant, prolonged freezing temperatures can damage them, so protection is advised in colder climates. High temperatures (above 90°F) can also cause heat stress.

Propagation: Easily propagated from cuttings. Healthy stem segments can be cut, allowed to callous for a few days, and then planted in well-draining soil. They can also be grown from seeds, though this is a slower process.

Pests and Diseases: Watch out for common cactus pests like mealybugs, scale insects, and spider mites. Good airflow helps prevent fungal issues.

Nomenclature Note:

It's worth noting the ongoing debate in botanical classification regarding Trichocereus and Echinopsis. While traditionally known as Trichocereus Pachanoi, many botanists now classify it under the genus Echinopsis, making the accepted scientific name Echinopsis Pachanoi. However, in horticultural and enthusiast circles, the name Trichocereus Pachanoi remains widely used. Regardless of the scientific classification, 'Cactus Kate Pachanoi' refers to a specific, recognized clone within the broader San Pedro cactus group
