Aloe Castilloniae

Copiapoa dealbata

A highly sought-after Chilean cactus admired for its distinctive, sculptural form and beautiful blue-grey to chalky-grey colouring. Copiapoa dealbata typically develops a compact, rounded body with pronounced ribs and a striking, almost powdered appearance.

A superb choice for collectors of rare and unusual cacti. It prefers strong light, excellent ventilation and an extremely well-draining, mineral-rich growing medium. Water sparingly during the growing season, allowing the soil to dry completely between waterings, and keep almost completely dry during winter.

Coryphantha elephantidens cv. Tanshi Zougemaru inermis is a rare, spineless cultivar of Coryphantha elephantidens, originally native to central Mexico, especially in Jalisco and surrounding regions. This particular cultivar is known for its smooth, rounded, and highly symmetrical tubercles (bumps) that give it a sculpted, almost “puffy” appearance.

Unlike the typical species, the inermis form lacks spines, making it especially attractive to collectors. It may produce large, showy pink to magenta flowers in summer. It prefers full sun to light shade, well-draining soil, and minimal watering.

Agave titanota ‘Compacta’ is a highly ornamental, slow-growing agave native to Oaxaca, Mexico. It is a cultivated selection of Agave titanota, valued for its tight, compact rosette form and heavily textured leaves.

Characteristics:

• Forms a dense, symmetrical rosette of short, thick leaves.
• Leaves are pale green to bluish-grey, often covered with a powdery bloom (farina).
• Margins are heavily armed with irregular, dark, sharp teeth.
• Terminal spine is strong and prominent.
• ‘Compacta’ forms a smaller, tighter growth habit than standard forms.
• Mature plants remain relatively low but become striking sculptural specimens.

Cultivation:

• Summer-growing succulent.
• Requires full sun for best form and coloration.
• Needs very well-drained, gritty soil (high mineral content preferred).
• Water moderately during active growth; very sparingly in winter.
• Sensitive to excess moisture, especially in cold conditions.
• Frost-tender; prefers warm climates.

Notes:

• The ‘Compacta’ form is a horticultural selection prized for its compact geometry and strong leaf armature rather than a distinct wild subspecies.
