Family: Cactaceae (Cactus Family)

Scientific name: Ferocactus schwarzii G.E. Lindsey 1955


Etymology: The species is named after its initial collector, Friedrich (Fritz) Schwarz.

OriginMexico (Central & northern Sinaloa Sinaloa)

Conservation status: Listed in CITES appendix 2.

 

 

(This Taxon belong to a group of six closely allied species. The group is: F. alamosanus, F. pottsii, F. schwarzii, F. reppenhagenii, 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 diameter
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.
Flowering phenology: This species blooms relatively early, when it reaches 12 cm in diameter.


"The particular characteristic of this species is that
the number of spines decrease as the plant ages"


Cultivation: Slow growing to start but does well under cultivation.  Use very draining soil, water during the aestival growth cycle (this plant need plenty of water) But needs to be avoided  wetting the bodies of these plants while they are in sunlight. A wet cactus in the sun light can cause sun burning which can lead to scares or even fungal infections and death.
Needs full sun. Keep dry at 10C in winter, but can tolerate sporadic light frost.

Reproduction: Seeds are the only way of reproducing.
