Curio herreanus 'Purple Flush'

Cultivated form and natural range of Curio herreanus 'Purple Flush'

Curio herreanus is native to Namibia, where it grows in desert and dry shrubland habitats.

‘Purple Flush’ is a cultivated form of Curio herreanus.

Care for Curio herreanus 'Purple Flush'

• Light and colour: Give ‘Purple Flush’ very bright light, including gentle direct sun after gradual acclimatisation. Strong light keeps the strands compact and brings out more burgundy-purple colour.
• Temperature and airflow: Avoid prolonged temperatures below 10 °C. Indoor temperatures of 18–27 °C suit this plant. Average to dry household air and gentle circulation around the crown help the potting mix dry evenly.
• Humidity: Aim for 40–50% humidity.
• Watering: Let the mix dry through and wait for the pot to feel light, then soak the root ball fully and drain it. Use pot weight and leaf firmness as guides between waterings.
• Potting mix: Use a fast-draining succulent mix with plenty of pumice, lava, grit or perlite.
• Feeding: Use a small amount of dilute succulent fertiliser occasionally while new stems and leaves are growing.
• Display: Give the stems room to trail from a hanging container or shelf. A hoop or trellis can guide them upward.
• Repotting: Use a slightly larger container when the root ball fills the pot. Replace old gritty mix if it packs down and absorbs water unevenly, keeping the container sized to the roots.
• Pruning: Trim a long or sparse strand above a healthy node to encourage branching.
• Propagation: Lay cut stem sections across gritty mix so several nodes touch the surface.

Sorting out colour, growth and pest problems on ‘Purple Flush’

• Fresh growth staying mainly green: Mainly green new growth usually points to light that is too weak to bring out the purple tones. Increase light gradually and watch the next section of stem for deeper burgundy-purple colour.
• Wrinkled or slightly flattened leaves: If the potting mix has dried through and the container feels noticeably lighter, watering is due; root damage can leave the leaves shrivelled afterwards. Check the roots and potting mix first. If the mix is dry and the roots feel firm, soak the pot thoroughly.
• Soft glassy leaves or a dark collapsing crown: Rot is likely when leaves become glassy or the crown turns dark and collapses. Inspect stems and roots. Cut every soft brown section back to firm tissue with a clean disinfected blade, discard the decay and re-root healthy pieces in fresh gritty mix.
• Wide gaps and thin new growth: Limited light often stretches new stems and widens the gaps between leaves. Move the pot closer to a bright window and increase direct light gradually so new sections develop denser leaf spacing.
• Cottony clusters or small scale-like bumps: Cottony clusters suggest mealybugs. Small fixed bumps suggest scale insects. Isolate the plant and inspect the stem and leaf bases. Clear away visible pests, then use a suitable product labelled for the confirmed pest. Follow the repeat interval on the label.
