Agave Utahensis var. Eborispina - A (Double Head)

$350.00

Agave Utahensis var. Eborispina - A stunning desert species prized for its tight rosettes of narrow, blue-green leaves tipped with long, elegant, ivory-colored terminal spines that can curl and twist dramatically with age. Native to the rugged limestone cliffs and canyons of the Mojave Desert, this slow-growing agave embodies a refined, sculptural beauty that contrasts with its harsh natural habitat. It thrives in full sun and extremely well-draining, rocky soil, tolerating cold temperatures down to around 10°F (–12°C) when kept dry. Highly sought after by collectors, A. utahensis eborispina is both delicate in appearance and remarkably resilient, making it a standout choice for arid gardens and alpine-style rock plantings.

🌞 Light

  • Full sun is essential — this agave develops its compact rosette, powdery white color, and bold leaf contrast only in strong, direct light.

  • Indoors: place near a south-facing window or use high-intensity grow lights.

  • Outdoors: ideal in open, unshaded positions with good airflow.

  • Partial shade can be tolerated but will produce longer, greener leaves.

💧 Water

  • Very drought-tolerant once established.

  • During active growth (spring to early fall):

    • Water deeply but infrequently — allow soil to dry completely before watering again.

    • In hot weather, about once every 10–14 days is sufficient.

  • During winter or cool dormancy:

    • Water lightly every 4–6 weeks or not at all if kept cool and dry.

  • Overwatering causes leaf yellowing, rot, or softening — dryness is safer.

🌵 Soil

  • Requires excellent drainage — it naturally grows on limestone cliffs and rocky slopes.

  • Ideal soil mix:

    • 60–70% pumice, lava rock, or coarse sand

    • 30–40% cactus or succulent mix

  • You can add crushed limestone or dolomite for an alkaline boost.

  • Avoid heavy organic or peat-based soils.

🌡️ Temperature

  • Hardy to about 10°F (–12°C) if kept dry. Protect from cold, wet conditions or bring under cover during prolonged freezes.

🍃 Fertilization

  • Feed lightly during active growth (spring–summer):

    • Use a diluted cactus or succulent fertilizer (¼ strength) once monthly.

  • Avoid high-nitrogen fertilizers — they cause weak, overly green growth.

✂️ Maintenance

  • Remove old, dried lower leaves only when they detach easily.

  • Avoid touching the leaf surface too much — it has a natural powdery “bloom” that protects it from sun and gives the white coloration.

  • Handle with care: spines are sharp and hooked.

🌱 Propagation

  • Propagated mainly by offsets (pups) — though FO-76 can be slow to produce them.

  • Use clean tools, allow offsets to dry for 2–3 days before potting.

  • Root in a warm, bright environment with minimal water until growth resumes.

🪴 Container Tips

  • Use clay or unglazed pots to encourage evaporation and airflow.

  • A shallow, wide pot works well to show off the rosette.

  • Repot only every 3–5 years, as FO-76 prefers being slightly root-bound.
