Plant Needs
Sunlight
Full sun exposure is required for optimal photosynthetic growth; tolerates brief periods of partial shade but may become leggy with prolonged shade
Watering
Extremely drought-tolerant; water sparingly only when the top 10–15 cm of soil is completely dry to prevent root rot
Temperature
Tolerates extreme temperature fluctuations, including light frosts down to -5°C; avoid prolonged exposure to temperatures above 35°C to prevent stem damage
Characteristics
- Stem: Green, jointed photosynthetic stems replace leaves; segmented into nodes and internodes
- Leaf: Reduced to small, scale-like bracts at stem nodes
- Reproductive structures: Dioecious; male cones are small, yellowish; female cones produce fleshy, berry-like seeds
Care Guide
Watering
Water once every 10–14 days; allow soil to dry completely between waterings
Fertilization
Diluted low-nitrogen liquid feed once every 6 weeks. Use only diluted, low-nitrogen fertilizers to avoid promoting soft, disease-prone growth
Eggshell powder topdressing：Crush dried eggshells into fine powder; sprinkle lightly on soil surface to add calcium without altering soil pH; avoid overapplication to prevent nutrient buildupPruning
- Remove dead or damaged stems in early spring to encourage new growth
- Thin overcrowded stems to improve airflow and light penetration
- Trim to maintain desired compact shape; avoid heavy pruning of mature woody stems
Toxicity
Warning: this plant may be toxic.
Pets & Humans
Pets: ASPCA: Toxic; ingestion may cause tremors, tachycardia, hyperactivity, vomiting, and seizures in severe cases
Humans: Contains ephedrine and pseudoephedrine; ingestion can cause increased blood pressure, palpitations, anxiety, and nausea; overdose may be fatal
Garden Uses & Culture
Culture: Traditionally used in Andean folk medicine for respiratory issues, but modern use is restricted due to toxic alkaloid content
Usage: Xeriscaping ornamental plant; historical medicinal use (now regulated in many regions)
