Curio acaulis, formerly known as Senecio acaulis, is a small succulent shrub with erect grey-green leaves with longitudinal lines. The leaves are cylindrical, elongated, slightly curved inwards, up to 4 inches (10 cm) long, and up to 0.2 inches (0.5 cm) in diameter. The solitary heads of yellow flowers are up to 0.4 inches (1 cm) in diameter and appear on up to 12 inches (30 cm) tall stems in spring.
The specific epithet "acaulis (a-KAW-liss)" is a New Latin adjective derived from the Ancient Greek "ἄκαυλος." It means "stemless" or "having no stem or stalk" and refers to the growth habit of the species.
How to Grow and Care for Curio acaulis
Light: Keep your C. acaulis in partial shade if outdoors and bright sunlight if indoors. Avoid intense afternoon sun in summer. It will grow in full shade but will become lank and leggy.
Soil: As with most succulents, this plant prefers a well-draining soil mix. For growing C. acaulis indoors, it is essential to use a container with at least one drainage hole at the bottom.
Hardiness: C. acaulis can withstand temperatures as low as 25 to 50 °F (-3.9 to 10 °C), USDA hardiness zones 9b to 11b. The plant will not survive consistent temperatures below freezing.
Watering: Water regularly during the growing season, allowing the soil to dry out between waterings. This plant is drought tolerant, but the soil should never be left dry for too long. Reduce watering frequency during the winter months. Water only if the soil is completely dry.
Fertilizing: C. acaulis can take a bit more fertilizer than other succulents if you want it to grow fast. Feed your plant once a year with a dilute solution of a balanced, water-soluble fertilizer in summer.
Repotting: You do not need to repot this plant often. You can do it when you see that the container becomes too small or shallow.
Propagation: This plant can be grown from seeds or cuttings. Seeds need warm temperatures or using seed warmer and constant moisture to germinate. Take cuttings during the spring and summer.
