Arizona Snowcap is a small ornamental cactus belonging to the Cactaceae family and is a mutated variant of Mammillaria gracilis. Under favorable conditions, it can grow a little faster and be more abundantly covered with dense thorns. Today, the plant is popular and common in many countries, as it has an impressive and unusual appearance and is easy to care for.
Mammillaria vetula subsp. gracilis 'Arizona Snowcap' can be easily identified by its cylindrical or spherical dark green stem, which is almost completely covered with white spines.
It usually grows to 3 inches (8 cm) long and 1 inch (2.5 cm) wide and has a strong lateral offset. The spines are short, numerous, bright white, and arranged extremely densely, creating a snowy appearance. Flowering occurs in spring and summer; small flowers have a bell-shaped shape and a large number of petals. The color can be bright yellow or pinkish-white with a pronounced brown stripe in the middle.
