# Tamaulipas Living Rock (Ariocarpus agavoides)

> Native to Tamaulipas, Mexico, Ariocarpus agavoides is an endangered geophytic cactus whose elongated, divergent tubercles resemble miniature agave rosettes. Most of its mass is stored in a massive subterranean taproot, and in late autumn it produces spectacular, vibrant magenta-pink diurnal flowers from its woolly apex.

## Light & Sun Exposure

Bright, filtered sunlight or direct morning sun; shield from scorching summer midday sun to prevent epidermal burning of the tubercles.

## Watering Schedule & Method

Thorough soak-and-dry protocol during the growing season; withhold water completely throughout the winter rest period to prevent root rot.

## Soil & Gritty Mix Formula

80% Porous mineral grit (pumice, crushed limestone, zeolite, lava rock) + 20% screened cactus peat; deep pots are essential for taproot development.

## Cold Tolerance & Overwintering

-2°C (USDA Zone 9b), provided the soil is kept entirely bone-dry.

## Propagation Methods

Exclusively by seed (sown in spring at 20-25°C in sterile conditions); seedlings are frequently micro-grafted onto hardy rootstocks to boost slow growth.
