🌱 Morphology
    A collector's Haworthia that forms compact rosettes of thick, fleshy, rounded leaves with blunt tips and translucent windows that allow light to pass into the inner tissues. Its most prized feature is its very dark green, purplish-grey or purple, coloration, which can intensify under abundant, filtered light. The leaf windows feature delicate lines and a transparency that contrasts with the dark epidermis, creating a smoked-glass effect. The densely arranged leaves form a highly attractive geometric rosette. It can produce basal offsets and form clumps over time. The intensity of the color depends on the clone and the light, temperature, and growing conditions.

🌍 Origin, habitat, and family
‘OB-1’ is a horticultural selection widely propagated among Japanese and Asian collectors, associated with the group of purple-colored obtuse haworthias, known in Japan as Murasaki Obutsu. OB-1 is a clonal code, not a botanical locality or an independent wild species. The name Haworthia ikra is used here in accordance with the taxonomic criterion adopted by DesertSTORE for this group.

Haworthias from this complex originate from South Africa, where they grow in stony ground and among low vegetation, with partial protection from direct sunlight. Dry periods alternate with spells of moisture that allow growth to resume. In cultivation, keeping the roots well-aerated and avoiding persistent moisture is essential to keep the plant healthy and its leaf windows in good condition.

Family Asphodelaceae, tribe Alooideae, genus Haworthia.

❄️ Temperature — USDA 10a
Tolerates minimum temperatures close to −1 °C for short periods, provided the substrate is dry and the plant remains protected from prolonged frosts. Cold combined with moisture can cause damage to the roots and leaf tissues.

☀️ Lighting
Prefers abundant, filtered light or bright partial shade. A DLI PAR of 8–15 mol/m²/day helps maintain a compact rosette and enhances the dark and purplish hues. Color intensity may increase under brighter light, but excessive direct sunlight can cause burns and stress. Gradual acclimatization is recommended.

💧 Growth cycle and watering
Relatively dormant in summer. During periods of intense heat, growth may slow. Water thoroughly when the substrate is dry and allow it to dry out completely before watering again. In summer, water less frequently, especially during heatwaves. At moderate temperatures, growth may resume, so watering should be adjusted to its actual activity. A well-draining substrate and good aeration are essential to prevent root rot.

🌸 Flowering
Produces a slender, elongated inflorescence with small tubular flowers in white, marked with greenish or brownish lines. Flowering is inconspicuous and usually occurs when the plant has favorable growing conditions.

🌿 Nutrition
During the active growing season, Desert CHOICE® Aloes, Haworthias & Co. is recommended, with a high content of potassium and bioavailable calcium. Apply with watering, and reduce or suspend fertilization during summer dormancy.
