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 in spring on up to 12 inches (30 cm) tall stems.

The specific epithet "acaulis" means "stemless," and derives from the Greek prefix "a," meaning "not or without" and the Latin noun "caulis," meaning "stem or stalk."

How to Grow and Care for Curio acaulis

Light: Keep Curio plants in partial shade if outdoors, which is their preference in summer, and bright sunlight if indoors. They will grow in full shade but will become lank and leggy.

Soil: These plants prefer well-draining soil. For growing Curio indoors, it is essential to use a container with at least one drainage hole at the bottom.

Hardiness: Curio acaulis can withstand temperatures as low as 25 to 50 °F (-3.9 to 10 °C), USDA hardiness zones 9b to 11b.

Watering: Curio plants are drought tolerant, but the soil should never be left dry for too long. They do need some water during the growing season but be careful not to leave the soil wet for prolonged periods.

Fertilizing: The members of this genus can take a bit more fertilizer than other succulents if you want them to grow fast.

Repotting: You do not need to repot Curio plants often. You can do it when you see that the container becomes too small or shallow.

Propagation: These plants can be grown from seeds or cuttings.
