About Curio amaniensis – Blue Chalk Fingers
Curio amaniensis (formerly Senecio amaniensis), commonly known as Blue Chalk Fingers, is an evergreen succulent prized for its upright blue-grey foliage and strong architectural form. The thick cylindrical leaves develop a distinctive powdery blue coating that provides exceptional colour contrast in the landscape. Its compact, clumping habit creates year-round structure and texture, making it a standout choice for contemporary and waterwise gardens.
It performs best in full sun and free-draining soils, thriving in coastal, Mediterranean, and dry inland climates. The foliage develops its strongest blue colouring when grown in bright sunlight. Once established, Blue Chalk Fingers develops excellent drought tolerance and requires very little maintenance, making it ideal for low-water-use landscapes and decorative container plantings.
They look excellent when used in succulent gardens, rockeries, coastal landscapes, decorative containers, and waterwise gardens where distinctive foliage colour and architectural form are desired. Its compact growth habit and year-round visual appeal make it suitable for both residential and commercial landscape projects.
