Safety

People: The foliage and unripe berries contain oils that can cause skin irritation or internal distress if ingested in large quantities.
Pets: This plant is generally considered non-toxic to cats and dogs, though ingestion of large amounts may cause mild digestive upset.
Children: The sharp, pointed needles pose a physical injury risk to small children if handled improperly.
Contact allergens: The sharp, needle-like leaves can cause mechanical skin irritation or contact dermatitis in sensitive individuals.
Airborne allergens: The pollen produced by male plants can be a significant allergen during the spring release period.
Edibility: Only the mature, dark blue berries of specific varieties are safe for consumption, as many other juniper species are toxic.

Growing it

Propagation: seed, cuttings
When to plant: spring, autumn
Overwintering: It is extremely cold hardy and requires no special protection during winter. Ensure the soil remains well-draining to prevent root rot during wet winter months.
In containers: It grows well in large containers, provided the pot has excellent drainage and is at least 40 cm wide.

Semi-hardwood cuttings

Take 10 cm cuttings in late summer.
Remove lower needles and dip in rooting hormone.
Place in a moist, sandy potting mix.
Keep in a bright, cool location until rooted.

Group this plant with other drought-tolerant species that enjoy full sun and lean soil conditions.
