Plant Needs
Sunlight
Requires full, unfiltered sunlight; tolerates intense desert UV exposure without shade
Watering
Extremely drought-tolerant; water only when soil is completely dry to avoid root rot
Temperature
Hardy to cold desert winters and hot summer heat; withstands frost down to -15°C
Characteristics
- Leaf: Reduced to small, scale-like bracts in whorls of 3; photosynthesis occurs primarily in green stems
- Stem: Green, jointed, cylindrical stems that function as the main photosynthetic organs
- Cones: Male cones are small, yellow, and pollen-producing; female cones develop into fleshy, red berry-like seed structures
Care Guide
Watering
Water sparingly once every 2–3 weeks
Fertilization
No regular fertilization needed. Fertilization can disrupt natural drought adaptation and cause excessive, weak growth
Eggshell powder topdress：Sprinkle finely ground eggshells on the soil surface once every 6 months; no dilution requiredPruning
- Remove dead or damaged stems in early spring to maintain a tidy shrubby form
- Thin overcrowded growth to improve airflow and reduce pest risk
- Avoid heavy pruning, as the shrub has slow regrowth and may become stressed
Toxicity
Warning: this plant may be toxic.
Pets & Humans
Pets: ASPCA: Toxic; ingestion may cause tremors, elevated heart rate, and restlessness
Humans: Contains ephedrine, a stimulant; ingestion can cause cardiovascular issues, anxiety, and overdose-related cardiac risk
Garden Uses & Culture
Culture: Used by Indigenous North American peoples for medicinal teas; also called Mormon tea for historical use by early settlers
Usage: Ornamental desert landscaping; historical medicinal use (modern use is restricted due to ephedrine content)
