What does Ferocactus townsendianus look like?
It forms a spherical to cylindrical barrel-shaped stem with pronounced ribs and heavy spines. Mature plants can produce yellow flowers near the growing point, followed by fruit if pollination occurs.
How much sunlight does Ferocactus townsendianus need?
It is a full-sun cactus and generally needs several hours of direct light to maintain compact growth and strong spination. Plants moved suddenly from shade into intense sun can scorch, so acclimatization is sensible.
How is Ferocactus townsendianus different from a common nursery barrel cactus?
The name refers to a particular Baja California taxon, while nursery plants sold as barrel cactus may belong to species such as Ferocactus wislizeni or Ferocactus cylindraceus. Reliable identification requires comparing the rib count, spine structure, flowers, and locality rather than relying on the common name alone.
