Blue Chalksticks Overview

Curio talinoides var. mandraliscae was previously known as Senecio mandraliscae. It is commonly called Blue Chalksticks, after the leaves. This succulent is interesting as it grows in the winter and is dormant during the summer months. Blue Chalksticks is a succulent perennial also known by the name Blue Senecio. Foliage is evergreen, silvery blue-green in colour and the finger-shaped, fleshy leaves are arranged oppositely. Flowers are small and white, these are produced in the summer. It has a spreading habit and typically forms short, dense mats. It may be used as groundcover in mild climates, it's half-hardy and can cope with temperatures as low as -7 degrees Celcius. A good choice for planting in a rock or succulent garden and a water-wise choice as it can survive periods of dry weather. Grows well in dry, sandy soil that readily drains, in full or partial sun.

How to propagate Blue Chalksticks

Cuttings

Can be easily propagated from leaf or stem cuttings, simply remove cleanly from the mother plant, let callus for a few days until the wound has closed and place on soil or in water and wait for roots to develop. Roots usually grow first to seek out water, followed by new leaves. This may take anywhere from a week to a few months.

Division

Divide offsets when they become too overcrowded. Allow the soil to dry, lift the plants and gently ease the roots apart, then replant. When taking offsets, use a sharp knife or secateurs and cut as close to the mother stem as possible to include as many roots as possible, then pot up.
