Echinopsis terscheckii, also known as Trichocereus terscheckii, cardon grande cactus or Argentine saguaro, is a large columnar cactus that is native to South America. It's common in Northern Argentina, to the dry slopes of the Andes in Peru, Bolivia, and Ecuador. It is a wide growing species with branches around 10 inches in diameter. Mature plants can grow over 25ft high. E. terscheckii typically has 8 to 14 ribs and green to light green flesh with yellow to white spines. The night blooming flowers are white and can grow 6 to 8 inches in diameter. This cactus is iconic within the native regions and has some history of use in local traditional medicine, though most commonly the cactus is grown as an ornamental. USDA hardiness zones 8-11.
Echinopsis terscheckii seeds should be spread across the surface of a sterilized cactus substrate mix. Cover the seeds with a thin layer of substrate mix and mist the surface to settle down the soil and seeds. Cover with a humidity bag, dome, or plastic wrap. Keep in a warm place with partial shade. Seeds will germinate best with high temp in the day and low temp at night. Seeds should germinate within 7-20 days. Mist or bottom water when the soil is almost dry. Even with optimal conditions, some seeds may have slow and sporadic germination. Place established plants in full sun to partial shade. Too much shade will make cactus and succulents etiolate during growth.
