Description: Echinopsis chiloensisSN|7742]]SN|7742]] var. eburnea previously known as Trichocereus chiloensisSN|7744]]SN|7744]] var. eburneus is very much like that of standard Echinopsis chiloensisSN|7742]]SN|7742]] but shows stouter ivory spines. The fruit and seed are similar to those of the other Varieties. Nowadays this plant is not considered a distinct variety but only one of the variable phenotypes of this this clinal species.
Growth Habits: It is a fiercely spiny cactus that develops into a shrub or small tree.
Stem: Rarely single, usually of several branches, sometimes of many, arising from near the base, starting nearly at right angles to the main trunk but soon erect, up to 8 m tall, stems 10-12 cm in diameter.
Ribs: 10 to 17 low and broad, separated by narrow intervals, divided into large tubercles even when fully mature.
Areoles/Spines: Areoles large whitish, 2 cm apart. Spines ivory, stout, at least when young, greyish later; 1 to 4 centrals, porrect, 5-7 cm (or even 12 or more cm long) 8 to 12 radials, up to 4 cm long.
Flowers: Flowers open during the day, white, 14 cm long, outer perianth-segments white but tinged with red or brown; inner perianth-segments white, acuminate.
Sun Exposure: Outside full sun or afternoon shade, inside needs bright light, and some direct sun.
Subspecies, varieties, forms and cultivars of plants belonging to the Echinopsis chiloensis group
- Echinopsis chiloensis (Colla) H.Friedrich & G.D.Rowley: It is a fiercely spiny cactus. Like it's relatives, this species is a quick grower and is reported to grow into a shrub or small tree up to 8 m in height. Distribution: coastal cordillera of Chile (North-Central Valley of Chile)
- Echinopsis chiloensis var. borealis (F.Ritter): can produce very long spines, up to 25 cm long. Distribution: Elqui valley, Huanta, Coquimbo, Chile
- Echinopsis chiloensis var. eburnea (Phil. ex K.Schum.) H.Friedrich & G.D.Rowley: This is the stouter spined form with impressive and showy ivory spines and all spines long; flowers pinkish. Distribution: East of Los Patos, bottom of valley, Coquimbo, Chile.
- Echinopsis chiloensis subs. litoralis (Johow) M.Lowry: is shrubby with arching or erect cylindrical branches less than 2 m tall. Its has much shorter, thinner and flexible spines. Distribution: coast north of Valparaiso (Atacama, Coquimbo).
- Echinopsis chiloensis var. panhoplites (K.Schum.): Young spines almost black, central spine very long. Distibution: Ovalle, Coquimbo, Chile.
- Echinopsis chiloensis var. pycnacantha (Salm-Dyck): spines very short and thick.
- Echinopsis chiloensis subs. skottsbergii (Backeb. ex Skottsb.) G.J.Charles
Notes: The original name for this cactus was Trichocereus chiloensis. In 1950, Skottsberg pointed that the name was misspelled, and was changed to "chilensis" for "Chile"+"ensis". The rules of nomenclature now, give priority to the original name, misspelling included, except if the name was changed by the original author. Thus, Friedrich & Rowley retained "chiloensis" when they included the genus Trichocereus into the genus Echinopsis.

Cultivation and Propagation: Trichocereus chiloensisSN|7744]]SN|7744]] is very easy to grow and cold hardy as low as -12°C (or less). Need a fertile, well drained soil mix. Water the plants well and allow them to dry before watering again. This species seems to do better with a little more water than most cacti. In fact, its cultivation requirements are really more like 'normal' plants than most other cacti. During the growing season fertilize them monthly with a balanced fertilizer
Sun Exposure: Outside full sun, inside needs bright light, and some direct sun. During winter month, put them in a cool luminous place and encourage them to enter winter dormancy by withholding water and fertiliser over the winter as they will etiolate, or become thin, due to lower levels of light.
Pest smd diseases: They are susceptible to fungal diseases if overwatered, but are not nearly as sensitive as many other cacti, especially in warm weather. They tend characteristically towards black rotted spots unless watering is moderate and only in hot weather, if kept damp through cold periods, they will invariably suffer.
Growth rate Trichocereus chiloensisSN|7744]]SN|7744]] produces noticeable amounts of growth each year if kept well fed and watered throughout the warmest months, particularly if it has been acclimatised to accept full sun. Once this cactus is established it can easily produce 20 cm of growth every year.
Propagation:: Cutting or from seed. The seeds are quite easy to germinate and grow. Their main requirements consist of high humidity levels, free-draining soil mix, and enough water, light, and nutrition.
