Commiphora Holtziana - A

$1,000.00

Commiphora Holtziana - A hardy, drought-tolerant frankincense relative native to East Africa, known for its sculptural, contorted branching and pale, papery bark that peels to reveal greenish to copper tones beneath. It typically forms a thick, swollen trunk with a smooth, bottle-like base, giving it strong caudiciform appeal for collectors. Leaves are small, bright green, and often trifoliate, appearing during the rainy season before dropping in dry periods. The plant exudes an aromatic resin when cut, characteristic of the Commiphora genus. Highly adaptable to arid climates, C. holtziana thrives in full sun, heat, and rocky soils, making it a resilient and attractive species for bonsai, xeric gardens, and pachycaul collections.

🌍 Origin & Habit

Commiphora kataf from Somalia is a semi-deciduous caudiciform shrub or small tree native to rocky, arid habitats. It forms a thick, water-storing trunk with peeling papery bark in pale cream, gray, or copper tones. Its branches are often gnarled or zigzag-shaped, with small, trifoliate leaves that appear briefly during the growing season.

This species is closely related to frankincense and myrrh trees (Burseraceae family), producing aromatic resins when cut.

☀️ Light Requirements

  • Full sun to bright light is essential.

  • Outdoors, provide 6–10 hours of direct sunlight daily.

  • Indoors, use a south-facing window or strong grow light (≥ 10,000 lux).

  • Insufficient light leads to weak, elongated growth and dull bark color.

🌡️ Temperature & Climate

  • Optimal range: 75–95°F (24–35°C).

  • Can tolerate up to 110°F (43°C) if well-rooted and ventilated.

  • Minimum temperature: 45°F (7°C); avoid prolonged cold or frost.

  • During dormancy (cool, dry months), keep it above 50°F (10°C).

💧 Watering

  • Active growing season (warm months):

    • Water deeply but infrequently.

    • Allow the soil to dry completely between waterings.

    • Typical rhythm: every 10–14 days in heat, depending on pot size.

  • Dormant season (cool or leafless period):

    • Reduce watering drastically or stop entirely until new growth appears.

    • Too much moisture when dormant can cause root or trunk rot.

  • The Somalia form is especially sensitive to overwatering.

🌱 Soil Mix

  • Requires a fast-draining, gritty mix.

    • Example blend:

      • 50–60% coarse pumice or perlite

      • 30% lava rock or coarse sand

      • 10–20% organic matter (e.g., cactus compost or fine bark)

  • Avoid peat-heavy soils — they retain too much water.

🍽️ Fertilizing

  • Feed lightly during the active growing season only.

  • Use a diluted, low-nitrogen fertilizer (e.g., ¼ strength cactus formula).

  • Overfeeding leads to leggy, weak growth and poor caudex shape.

🌿 Pruning & Shaping

  • Commiphora kataf can be pruned to enhance its sculptural form.

  • Remove leggy or crossing branches in spring before growth begins.

  • The bark scars beautifully, often healing into attractive textures.

🪴 Repotting

  • Repot every 2–3 years in late spring.

  • Handle roots gently; avoid removing too much of the fine root system.

  • Always use a well-ventilated pot with large drainage holes.

  • Clay or terracotta pots are preferred for their breathability.

🌸 Seasonal Cycle

  • Spring–summer: Active growth; leaves appear, sometimes followed by small, inconspicuous flowers.

  • Late summer–autumn: Leaves begin to yellow and drop as the plant enters dormancy.

  • Winter: Rest period — keep dry and warm.

⚠️ Common Issues

  • Overwatering: The most frequent cause of death — trunk or root rot.

  • Cold exposure: Causes defoliation and stem dieback.

  • Low light: Leads to elongated, weak stems and faded bark.

  • Pests: Occasionally affected by mealybugs or spider mites; treat with neem oil or insecticidal soap.

🌸 Bonus Tip

The peeling bark is a hallmark of healthy Commiphora kataf. If bark shedding slows or stops, it often signals insufficient light or overwatering.
