Agave titanota ‘White Ice’, also known as White Ice Titanota, is a rare, prized cultivar of Agave titanota with a frosty white to spooky blue-white rosette and dramatic black spines.

Origin

• This is a selected cultivar of Agave titanota, which occurs naturally in Mexico, specifically in the dry highlands of Oaxaca.
• The wild species grows on rocky slopes, limestone cliffs, and dry grasslands; adapted to extreme drought, heat and frost; ‘White Ice’ is purely an ornamental selection from the modern succulent trade.

Care

• Grows slowly into a compact, usually solitary rosette about 45–60 cm high and 60–90 cm wide (sometimes up to 1 m); leaves thick, broad, short, ghostly white-blue with wax coating, black marginal teeth and a long terminal spine.
• Prefers full sun colors intensify in bright sunlight; Light partial shade possible but full sun gives the best contrast and compact growth.
• Plant in very well-drained soil (sandy-gravelly, cactus/succulent mix with pumice or perlite); pH neutral to slightly alkaline; Avoid heavy clay or wet feet (root rot risk).
• Watering: extremely drought tolerant; soak-and-dry method — allowing soil to dry completely between waterings; keep sparingly in the growing season (spring/summer), keep almost dry in winter; Overwatering is fatal.
• Winter hardiness: good (USDA zones 8a–11); tolerates frost down to about -6 to -12 °C in colder climates (such as the Netherlands) as a container plant for frost-free overwintering or heavy mulching.
• Fertilization: little to none; in case of emergency in spring, a low dose of diluted cactus fertilizer; avoid over-fertilization.
• Pruning: remove only dead leaves; Wear gloves and protective clothing .

Usage

• Mainly ornamental plant (ornamental): prized for architectural form, frosty white/blue-white color, symmetry and sculptural look with black spines; Perfect for drought-resistant gardens, rock gardens, borders, containers, succulent gardens or as a collector’s item/focal point.
• Attracts attention in xeriscape and desert landscapes; after many years (20–30+) produces a tall flowering stem (up to 3–6 m) with yellow flowers; Mother plant dies afterwards.
