  • Posted by Baja_Costero (Baja California - Zone 11b) on May 24, 2019 8:13 PM concerning plant:
    Common and durable golden-spined barrel cactus to 2-3 feet in diameter. Known as the asiento de suegra (mother-in-law's seat) in Mexico. Very spiny, with a wooly crown when mature. Yellow flowers and wooly fruit appear within that crown. 21-37 ribs, 3-4 central spines.

    Propagated from seed. Fast growing for a barrel cactus. Tolerates extreme heat and extreme exposure. Provide good drainage and strong light in cultivation. Expect maybe 20 years to sexual maturity.

    Extremely multiheaded versions of this plant are typically created by ablating the growth center and forcing branches, though there is normally some degree of occasional branching. The site of injury is completely hidden after a few years of growth. A white spined version (silver barrel?) exists, but the spines turn brown pretty fast, so it's not particularly silvery when mature.

    The golden barrel is nearly extinct in habitat due to the construction of the Zimapán dam in Hidalgo, but one of the most common cacti in cultivation. A second population far to the west of this area (in southwestern Zacatecas) was recently discovered.

    The genetics of this plant place it outside Echinocactus as it has historically been understood, and closer to Ferocactus. A new monotypic genus, Kroenleinia, was proposed for this plant in 2014, and it appears the new genus name has been accepted.
