Agave triangularis (5 and 15 gallons)

    Agave hanburyi, Agave horrida triangularis, Agave rigidissima, Agave kerkhovei, Agave regelliana, Agave triangularis var. subintegra, Agave triangularis var. rigidissima
  • Common Names:  
    Triangle Agave
  • Family:  
    Agaveacea
  • Origin:  
    This plant is indigenous to the arid calcareous mesa west of Tehuacan in southern Puebla, Mexico. It grows in heavily grazed areas alongside tree forms of Yucca periculosa and Lysiloma sp. as well as tree cactus and several other agaves.
  • Height:  
    4-6'
  • Width:  
    3-5'
  • Cold Tolerance:  
    20 to 25°F, -6.7 to -3.9°C
  • Heat Tolerance:  
    Very high heat tolerance
  • Light Requirement:  
    Full sun to light shade inland.
  • Water needs:  
    Very drought tolerant, but it grows faster in summer when given some irrigation.
  • Maintenance:  
    If desired, large clusters can be carefully divided, making sure to retain some roots with each part. The sharp terminal spines can be clipped.
  • Uses:  
    This is a handsome, ornamental medium-sized agave that's great in landscape borders, rock gardens, succulent gardens, raised planters or xeriscape plantings. Some leaves have teeth along their margins and a long spine at the tip so take care to locate this plant away from foot traffic. A. triangularis makes a dramatic statement in a large container as well. It is deer and rabbit resistant and it attracts nectar-feeding insects and birds when in bloom.
  • Propagation:  
    This agave can be propagated from seed or more easily from offsets which grow at the base of the rosette. They are easily removed and replanted.
  • Problems:  
    Requires soils with very good drainage. For best effect, protect leaves fromscar damage as they remain on the plant for years.
  • Special notes:  
    This agave has thick, rigid triangular shaped, mostly olive green leaves (some plants have bright apple-green coloring or fine brown red flecks). It has a more rugged look than many agaves. Agave triangularis rarely flowers.Lower leaves can be pruned on mature plants to expose leaf printed bark on stem.
