Family: Cactaceae (Cactus Family)


Conservation status: Listed in CITES appendix 2.

Origin: Catamarca, Argentina

Habitat:   Argentina is a land erupting in volcanic fire, quickly changing to the glacial cold of the Andes. Nearby is the most arid desert in the world, the desolate Puna de Atacama. Inhabitants must be very rugged in order to tolerate such extremes in exposure. Trichocereus grandiflorus is such a robust individual.
 

Growth Habits: T. grandiflorus is a basally branching columnar cactus, up to 90 cm tall.
Stems: 5-8 cm, in diameter.
Ribs: 12 to 18.
Areoles: Whitish brown.
Central spines: 1 to 2 , up to 6 cm long.
9 to 11 brownish
Radial spines:  Up to 4 cm inches long.
Flowers: 7-10 cm long, bright red produced near the end of the stems. Throat dark red, filaments fuchsia . Anthers  clear pastel and stigma pure white.
 

 


 

Remarks: The main form of T. grandiflorus has red flowers in summer, but forms with orange and yellow (T. huascha var. macrantha) flowers are also found.
This columnar species  has been the subject for years of intensive selective hybridization with hybrids of Echinopsis. As a result hybrids  (see: Trichopsis) now flower in a vast array of colours, including yellow, rose, crimson, orange, violet, white and even bicolour. Flowers can attain 22cm in diameter, rivalling even the giant flowers of the epiphytic "Orchid Cacti" (Epiphyllums). T. grandiflorus hybrids in time form attractive columns that explode yearly in vivid floral displays. Very few cacti can surpass the flowers of the T. grandiflorus hybrids for sheer flower power.
