Cactus Corral Argentinensis (Cuttings)

Cactus Corral Argentinensis refers to a specific cultivar of Trichocereus, which is a genus of columnar cacti native to South America. Here's what is known about it:

Origin and Background:

The "Cactus Corral Argentinensis" cultivar gets its name from "Cactus Corral," a cactus sanctuary in Sylmar, California. Cactus Corral was founded in 1951 and revived in 2018 by the Hernandez family.

This specific cultivar is likely a selection or hybrid that originated from Cactus Corral, possibly named for its "Argentinensis" lineage or characteristics. Cactus Corral explicitly mentions "The luminous Blue Peru Argentinensis" as a highlight of their collection, suggesting a connection to Trichocereus Peruvianus and its "blue" forms, possibly with an Argentine origin or appearance.

There's a discussion online among enthusiasts about a "Trichocereus hybrid cv 'Argentinensis'" which some suspect is a Peruvianus dominant and Validus recessive hybrid, due to its wispy spines and girth. This suggests that the "Argentinensis" designation might point to a specific type of genetics or appearance within Trichocereus varieties.

Characteristics:

Blue Hue: One of the most notable characteristics of 'Cactus Corral Argentinensis' (specifically the "Blue Peru Argentinensis" mentioned by Cactus Corral) is its ability to radiate a blue hue, especially when given partial shade. This glaucous, bluish color is highly sought after by collectors.

Columnar Growth: Like most Trichocereus species, it is expected to be a columnar cactus, growing tall and upright.

Spines: While not explicitly detailed for this specific cultivar, Trichocereus species generally have variable spines. The discussion of "wispy spines and girth" in relation to other 'Argentinensis' hybrids suggests this could be a characteristic.

Flowers: Trichocereus species are generally known for producing large, often white, nocturnal flowers that can be quite impressive.

Hardiness: Trichocereus cacti in general are known for their hardiness and ability to tolerate lower temperatures (down to 0°C to -5°C for weeks if kept dry) due to their native habitat in the Andean mountains.

Care (General Trichocereus Care, applicable to this cultivar):

Sunlight: Thrives in ample sunlight, preferably full sun during the growing season (April to October). Can tolerate partial shade, which may enhance its blue coloration. If grown indoors, a south or west-facing window is ideal.

Soil: Requires well-draining soil. A mix containing sharp sand, horticultural grit (pumice, akadama, crushed lava rock), and organic matter (like compost or worm castings) is recommended. Poor drainage can lead to root rot.

Watering: Water during the growing season (April to October) once to twice a week, ensuring the top inch of soil is dry before re-watering. Water less frequently, or not at all, during winter dormancy when temperatures drop.

Fertilizer: Fertilize during active growth (April to October) with low nitrogen at the start and end of the season, switching to a balanced 20-20-20 NPK feed during peak summer. Seaweed is also beneficial.

Dormancy: Benefits from a dormancy period in winter. Stop watering when nights drop to 10°C or below, and keep the plant in a cool, dry place with good airflow.

Potting: Regularly check if the plant needs more space. Mature plants can be planted in the ground if the soil is free-draining.

In summary, "Trichocereus cactus CV. 'Cactus Corral Argentinensis'" is a specific cultivar likely developed or popularized by Cactus Corral, known for its attractive blue hue, particularly when grown in partial shade, and sharing the general robust characteristics and care requirements of other Trichocereus species
