Ariocarpus retusus ssp. scapharostroides is a subspecies of Ariocarpus retusus, a species in the cactus family known for its unique and intriguing appearance. This particular subspecies is prized among cactus enthusiasts for its distinctive characteristics. Here’s an overview of its description and some tips for cultivating it successfully.

Description

Ariocarpus retusus ssp. scapharostroides distinguishes itself from the main species with several notable features:

• Body: It has a more elongated and somewhat tubular body shape compared to the typically more star-shaped form of Ariocarpus retusus. The body is green to blue-green, often taking on a slightly glaucous hue.
• Tubercles: The tubercles are long, narrow, and more pronounced, resembling the shape of a boat or canoe, which is referred to in the subspecies name 'scapharostroides' (scapha meaning boat and stroides meaning like). This feature makes it quite distinctive in appearance.
• Flowers: The flowers are similar to those of the main species, typically pink to white, and bloom in the late fall. They emerge from the woolly areoles at the crown of the plant.
• Size: It remains relatively small and compact, making it an ideal choice for cultivation in containers.

Cultivation Tips

Light: Ariocarpus retusus ssp. scapharostroides requires bright, indirect sunlight. Direct sunlight can cause sunburn, so it’s best to provide some shade during the hottest parts of the day, especially in summer.

Soil: A well-draining cactus mix is essential to prevent root rot. You can create a suitable mix by combining standard cactus soil with additional perlite or pumice.

Watering: Water sparingly. The soil should be allowed to dry out completely between waterings. Over the summer months, water can be applied more frequently, but always ensure the soil is dry before watering again. Reduce watering significantly during the winter months to mimic its natural dormant period.

Temperature: This subspecies is quite hardy but should be protected from frost. It prefers warm temperatures during the growing season and cooler, but not freezing, temperatures during its dormant period in the winter.

Fertilizing: Use a diluted, low-nitrogen cactus fertilizer during the growing season. Do not fertilize during the dormant winter period.

Repotting: Repotting is rarely needed due to its slow growth rate. If necessary, repot in the spring, being careful not to damage the root system.

Pests and Diseases: Keep an eye out for common cactus pests such as mealybugs and spider mites. Proper air circulation and avoiding water on the plant's body can help prevent fungal diseases.

Cultivating Ariocarpus retusus ssp. scapharostroides can be a rewarding experience due to its unique appearance and relatively low maintenance requirements. With proper care, this subspecies can thrive and become a standout addition to any cactus collection
