Echinocactus grusonii - Golden Barrel Cactus

Golden Barrel Cactus - Echinocactus grusonii

Echinocactus grusonii, commonly known as the Golden Barrel Cactus, is a distinctive, slow-growing species native to central Mexico. Recognised for its perfectly rounded shape and vibrant golden spines, this resilient plant thrives in arid environments and is a favourite in xeriscaping and desert gardens.

Distinctive Features

• Spherical Form: Naturally grows into a near-perfect sphere, which can reach up to 90 cm in diameter.
• Golden Spines: Sharp, yellow-gold spines cover the ribs, providing both protection and an iconic appearance.
• Woolly Crown: Mature specimens develop a dense woolly tuft at the apex, where yellow flowers emerge.

Care Tips

• Light: Requires full sun to thrive, with at least 6-8 hours of direct sunlight daily.
• Water: Low water needs; allow the soil to dry completely between watering.
• Humidity: Prefers dry conditions; high humidity can encourage rot.
• Media: Well-draining, sandy or rocky soil mix with perlite or pumice.
• Temperature: Tolerant of high heat but sensitive to frost; should be kept above 10°C.
• Fertiliser: Occasional feeding with a diluted cactus fertiliser during the growing season.
• Repotting: Infrequently needed due to slow growth, but ensure a well-draining pot.

Additional Notes

• Produces yellow flowers in summer, but only when mature (usually after 20 years).
• Highly drought-tolerant and ideal for rock gardens and container growth.
• Non-toxic but has sharp spines that require careful handling.

The Golden Barrel Cactus is a stunning and low-maintenance addition to any arid or succulent collection. Its symmetrical form and striking spines make it a favourite for both experienced collectors and beginners looking for an architectural plant.
