Curio haworthii – Waxier Blue-Grey Succulent from South Africa

Curio haworthii, formerly classified under Senecio, is a perennial succulent shrublet hailing from the Eastern Cape of South Africa. This compact, drought-hardy plant is cherished for its densely packed, blue-grey leaves that are covered in a waxy cuticle, helping reduce moisture loss. It’s an excellent candidate for dry landscapes and performs equally well in containers.

Distinctive Features

• Leaf Texture: Thick, spindle-shaped leaves with a prominent waxy coating that gives them a pale, silvery hue.
• Growth Form: Upright to sprawling stems forming a shrubby mound up to 30 cm tall.
• Seasonal Interest: Small, brush-like white flowers appear in late summer to early autumn, though the foliage remains the star.

Care Tips

• Light: Thrives in bright light to full sun, though can tolerate partial shade.
• Water: Water sparingly; allow the soil to dry out completely between watering sessions.
• Humidity: Prefers dry air; avoid high humidity environments.
• Media: Requires well-draining soil, such as a cactus or succulent mix with added grit or perlite.
• Temperature: Ideal range is 10–25°C; protect from frost.
• Fertiliser: Use a diluted cactus fertiliser during active growth, no more than once a month.
• Repotting: Repot every 2–3 years or when root-bound; ensure good drainage.

Additional Notes

• Excellent for rockeries, succulent borders, or as a sculptural indoor plant.
• Toxic to pets if ingested – keep out of reach of cats and dogs.

Whether displayed as a ground-hugging specimen in a dry garden or perched in a minimalist container, Curio haworthii offers year-round appeal with its frost-sensitive but visually captivating foliage. Its easy care requirements make it suitable for novice and experienced growers alike.
