Taxon belong to a group of six closely
allied species. The group is:
F. pottsii, F. schwarzii,
F. glaucescens, & F. echidne
Description: F. schwarzii is a solitary slow growing
barrel cactus that becomes nearly spineless when old making it a
handsome plant. At a first glance the mature specimens looks more like a
Echinocactus than a Ferocactus.
Stem: Deeply grooved and bright green, up to 80 cm tall, 50 cm in
Spines: Younger plants have usually 4 to 5 (or more) gold
coloured spines. As they age the number of spines decreases to 0-2. The
spines are needle-like, and are different than of most Ferocactus.
Flowers: Yellow 10 cm in diameter.
Blooming season: This species blooms relatively early, when
it reaches 12 cm in diameter.
Remarks: The particular characteristic of this species is that
the number of spines decrease as the plant ages.
