Agave havardiana is a succulent that can survive colder temperatures than many others. It forms a thick, compact, rosette of silvery-blue to gray-green, fleshy leaves. Leaves have teeth on the margins and a sharp spine at the end. Bright yellow to yellow-green flowers on a large stalk (that can reach 20′) appear once within 20-40 years. Excellent in xeriscapes, rock gardens, containers, and as a specimen plant. Effective in mass planting as a barrier. Needs excellent drainage and best in rocky or gravel soil. Tolerates alkaline conditions. Prefers full sun but can tolerate light shade. Monocarpic. Fire-resistant. Deer and rabbit-resistant. Cold hardy to -20°F.
