Curio herreanus 'Purple Flush'

A purple-tinged selection from a Namibian succulent

‘Purple Flush’ is a cultivated form of Curio herreanus, selected for bead-like to teardrop leaves that develop pronounced purple colouring. The species was formerly classified as Senecio herreanus and is still often known by that name.

C. herreanus is native to Namibia, where low succulent growth occupies dry, open ground among stones and sparse shrubs. Rain is limited and often separated by long dry intervals.

Trailing stems spread across the surface, while the thick leaves store water and their narrow translucent windows allow light into the inner tissue. The deeper purple colour is a cultivated trait; the water-saving leaf structure comes from this arid ancestry.

Care for water-storing roots and leaves

Renewing plum-coloured stems from healthy nodes

Display the plant hanging or across a shelf so its heavier teardrop leaves are not pressed against a wall. Carry the plant by the pot and crown, with trailing growth resting in loose loops.

Sunlight and the purple flush

Position Curio herreanus ‘Purple Flush’ directly at a bright east, south or west window, with gentle direct sun reaching the trailing foliage. Direct sun is useful for the plant after gradual acclimation.

Water cues from teardrop-shaped beads

Use pot weight and a probe to confirm that most of the mix around the plant is dry before watering. Give one complete soak, never a series of shallow splashes, and remove the runoff.

Sun, warmth and airflow around the trails

Steady indoor warmth suits active growth. In bright winter light, the plant can rest in a cooler, frost-free position if the root ball is kept drier.

Purple bead and stem problems in Curio ‘Purple Flush’

The teardrop beads develop purple stems and patches

Purple colouring is part of ‘Purple Flush’ and can vary with leaf age and growing conditions. Healthy pigment remains firm and follows the surface of the bead. Translucent or mushy purple-black tissue that expands from a wet stem base strongly suggests decay. Healthy purple colouring remains firm and dry.

The translucent line on each bead looks like a scar

The lengthwise window that admits light into the fleshy leaf is normal in this Curio group. It repeats on sound, firm beads and needs no treatment. Sunken or torn areas outside that regular line, especially after handling, are physical damage; soft spreading areas require a rot check.

Purple beads wrinkle although the compost feels damp

Avoid assuming the hanging ends need more water. Roots or the crown may have failed in wet mix, leaving the strands dehydrated. Trace a wrinkled vine back to the pot and check for firm stems and pale roots. Root healthy cuttings if the base is brown, hollow or soft.

The pot surface becomes bare while the ends keep growing

Older stems may stop rooting at the top and are easily dislodged from the mix. Coil firm sections back onto the surface and pin several nodes into contact so they can root, keeping the crown well lit. Remove any dead base first; layering a rotting strand only carries the problem across the pot.

Keep Curio herreanus ‘Purple Flush’ away from children and pets

• Keep this plant away from children, cats and dogs.
• Its effects after chewing or swallowing are unclear, and plant material can still cause an upset stomach.
• Contact a veterinarian or medical professional if symptoms develop or do not settle.

The meaning and history of Curio herreanus

Curio is linked to the Latin curiosus, meaning curious, in reference to the group's unusual forms. Herreanus honours Hans Herre.

Paul V. Heath established the genus Curio in 1997 in Calyx, volume 5, page 136.

Moritz Kurt Dinter first described it as Senecio herreanus in 1932 in Repertorium Specierum Novarum Regni Vegetabilis, volume 30, page 180. Paul V. Heath later placed it in Curio as Curio herreanus in 1999 in Calyx, volume 6, page 54.
