Huernia hystrix var. parvula Care Sheet

Common Names:

  • Little Porcupine Huernia

Scientific Name:

  • Huernia hystrix var. parvula


Huernia hystrix var. parvula, commonly known as Little Porcupine Huernia, is a small, stem succulent with distinctive, spiny, green to reddish-brown stems. It is known for its unique and striking star-shaped flowers, which are typically maroon or dark red with a glossy texture.

Light Requirements:

  • Indoors: Requires bright, indirect light. A south or east-facing window is ideal. Avoid direct midday sun as it can scorch the plant.
  • Outdoors: Prefers partial sun to light shade. If placed outdoors, gradually acclimate the plant to direct sunlight to prevent sunburn.


  • Ideal Range: 60-80°F (15-27°C)
  • Tolerance: Can tolerate temperatures down to 40°F (4°C) but should be protected from frost.
  • Indoors: Keep away from cold drafts and extreme heat sources.


  • Frequency: Water moderately during the growing season (spring and summer). Allow the soil to dry out between waterings.
  • Method: Water until it drains out of the bottom of the pot, then empty the drainage tray. Reduce watering in winter when the plant is dormant.


  • Prefers low to average humidity. High humidity and poor air circulation can lead to fungal issues.


  • Type: Well-draining cactus or succulent mix.
  • DIY Mix: Combine regular potting soil with sand, perlite, or pumice in a 2:1 ratio to enhance drainage.


  • Frequency: Fertilize sparingly. Once every 4-6 weeks during the growing season (spring and summer) is sufficient.
  • Type: Use a balanced, water-soluble fertilizer diluted to half strength. Avoid fertilizing in the dormant winter period.

Potting and Repotting:

  • Container: Use pots with drainage holes to prevent waterlogging.
  • Repotting: Repot every 2-3 years or when the plant becomes root-bound. Spring is the best time for repotting. Handle with care to avoid damaging the stems.

Pruning and Maintenance:

  • Pruning: Minimal pruning is required. Remove any dead or damaged stems to maintain plant health and appearance.
  • Propagation: Easily propagated from stem cuttings. Allow cut ends to callous over for a day or two before planting in dry soil.

Pests and Problems:

  • Common Pests: Watch for mealybugs and spider mites. Treat infestations with insecticidal soap or neem oil.
  • Problems: Overwatering can lead to root rot. Ensure proper drainage and allow soil to dry between waterings. Avoid high humidity and poor air circulation to prevent fungal issues.

Tips for Success:

  • Handle with care to avoid damaging the delicate stems and spines.
  • Rotate the plant periodically to ensure even light exposure and growth.
  • If grown outdoors, provide shelter from heavy rain and frost.
