Origin
The Astrophytum ornatum, also known as the Bishop's Cap cactus, originates from the North of Mexico, where it grows on lime-rich soils under subtropical conditions. The plant was first described in 1839 by the German botanist Albert Gottfried Dietrich. Since then, the Astrophytum ornatum has managed to spread to various other parts of the world, particularly thanks to the interest of cactus enthusiasts.

Characteristics
The Astrophytum ornatum is characterised by its cylindrical or conical growth pattern and can reach a height of up to 1 meter. The stems of the plant have large areoles, the places from which the spines emerge, which are covered with yellow, orange or white wool. The flowers of the Astrophytum ornatum are yellow with an orange or red core and can grow up to 9 centimetres in diameter. This makes the Astrophytum ornatum the largest plant of its genus.

Care
The Astrophytum ornatum requires well-draining soil, preferably a cactus mix, and must be placed in a planter with sufficient drainage to prevent root rot. Although the plant can tolerate some frost, it grows best at temperatures between 10 and 30 degrees Celsius. The Astrophytum ornatum needs full sun for optimal growth and flowering, but can also survive in partial shade. Generally, the plant needs little water, except during the summer months when it is actively growing.
