🌱 Morphology
    A collector's Haworthia, slow-growing and compact, especially prized for the size and relief of its leaves. These are arranged in two opposing rows, forming a geometric fan, and are extraordinarily thick, with dark green to nearly black sides. The ends are abruptly truncated and feature wide translucent windows, dotted with light spots and ridges that sparkle when hit by light. The rough, striated surface accentuates its stone-like appearance. As is typical of the species, new leaves appear in the center and develop toward both sides. Contractile roots can progressively pull the plant into the substrate.

🌍 Origin, habitat and family
'Mammoth' is a horticultural selection of Haworthia truncata, with no natural locality of its own and no confirmed breeding genealogy. The wild species is native to the Little Karoo, in the Western Cape, South Africa, especially around Oudtshoorn, Volmoed, Vanwykskraal, and Dysselsdorp. It grows in stony terrain, often partially buried and protected under small shrubs. Only the leaf windows protrude, which allow for light capture while reducing the exposure of the rest of the plant to the dry environment.

❄️ Temperature — USDA 10a
It is advisable to keep it above -1 °C, especially when the substrate is moist. Although it can withstand brief drops below this threshold when dry, it is preferable to protect it from prolonged frosts.

☀️ Lighting
It needs abundant, filtered light or soft sun with partial shade, avoiding sudden changes from shade to intense exposure. Adequate lighting promotes compact growth and allows one to appreciate the relief and transparency of its windows. Indicative DLI PAR: 8–15 mol·m⁻²·day⁻¹.

💧 Growth cycle and watering
Summer dormancy. Its growth is favored during cool seasons. In autumn, winter, and spring, it is recommended to water thoroughly and allow the substrate to dry before the next watering. During periods of intense heat, reduce water intake and maintain good ventilation. It is essential to avoid waterlogging.

🌸 Flowering
It produces a thin, elongated inflorescence with small, whitish tubular flowers, streaked with greenish or brownish lines. Flowering is discreet and takes a backseat to the size, relief, and luster of the leaf windows.

🌿 Nutrition
During the active growth period, Desert CHOICE® Aloes, Haworthias & Co. is recommended, with a high content of potassium and bioavailable calcium. It is applied with watering, reducing or suspending fertilization during summer dormancy.
