Twin-flowered Agave (Agave geminiflora) is a slow-growing, compact succulent (2-3 ft high/wide) known for its dense rosette of narrow, dark green, spine-free leaves. It thrives in full sun, requires minimal, low-water care, and is hardy to 20°F–25°F. It blooms once after 10-15 years, sending up a 10-18 ft spike of yellow, twin-paired flowers before dying.
