Echinocactus grusonii 'White Form' - White-Spined Barrel Cactus

Echinocactus grusonii 'White Form' is a breathtaking variation of the Golden Barrel Cactus, distinguished by its pristine white spines that contrast beautifully with its vibrant green, ribbed body. Native to central Mexico, this slow-growing, globular cactus thrives in arid conditions and makes a stunning addition to any xeric garden or indoor collection.

Distinctive Features

• Striking White Spines: Unlike the classic golden-spined variety, this form has delicate yet resilient white spines that give it an elegant, frosty appearance.
• Globular Growth Habit: Naturally forms a near-perfect sphere, which can reach up to 60 cm in diameter over time.
• Summer Blooms: Produces bright yellow flowers at its crown in mature specimens, adding a pop of colour to its refined look.

Care Tips

• Light: Requires full sun to maintain compact growth and vibrant spine colour.
• Water: Drought-tolerant; water sparingly, allowing soil to dry out completely between waterings.
• Humidity: Prefers dry conditions; avoid high humidity to prevent rot.
• Temperature: Thrives in warm temperatures between 20-35°C but can tolerate brief drops to 5°C.
• Fertiliser: Apply a diluted cactus fertiliser during the growing season (spring and summer) once a month.
• Potting: Use a well-draining cactus mix with added sand or pumice for aeration.
• Propagation: Grown primarily from seeds, with slow but rewarding growth.
