Argentine Saguaro
While technically not a saguaro, but a cardon, Argentine saguaro got its nickname from its appearance similar to the familiar saguaro from the Sonoran Desert.
Like the common saguaro, the Argentine saguaro is an iconic symbol of the desert. It is striking and bold, standing tall even against the harsh desert sun.
Botanical name: Leucostele terscheckii or Echinopsis terscheckii (previously named Trichocereus terscheckii)
Other names: Argentine cardon, cardon grande
TABLE OF CONTENTS
Argentine Saguaro Appearance
The Argentine saguaro stands upright and tall, growing branches to the side as it ages. Its tall, vertical trunk is round on the sides and contains 10-15 ribs.
A deep green body that turns into a muted green when it receives lots of suns. Long, golden spines that grow from white areolas.
Flowers bloom from late spring to early fall. Showy, white flowers that are 3 to 5 inches wide grow from the ends of the cactus stems.
Followed by green fruit that contains seeds.
Argentine Saguaro Landscaping Tips
A mature Argentine saguaro commands attention with its stature and height. To use it as a main focal point, plant alongside shorter desert plants such as cacti, agaves, and blooming desert shrubs.
When planting, allow for vertical clearance. It can grow 1-2 feet a year to reach over 40 feet in height.
Use rocks or other plants to provide shade when the plant is young.
Deep watering is critical for encouraging a healthy root system.
When in bloom, the Argentine saguaro attracts pollinators such as bees, butterflies, and birds. Birds and critters enjoy the fruits.
Argentine Saguaro Origin
Argentina and Bolivia, in warm and temperate areas that are mostly dry
Argentine Saguaro Care
Soil: Loose, well-draining soil that is moderately fertile.
Temperature: Can withstand temperatures down to 5 degrees Fahrenheit for a brief period of time.
Water: Apply occasional, deep watering. Allow the soil to dry out completely between waterings. Use a moisture meter or stick your finger through the soil to gauge the moisture level. It’s better to err on the side of underwatering than overwatering.
Sun: Full sun to partial shade
