Safety

People: The plant contains calcium oxalate crystals that can irritate the skin and mouth.
Pets: Yucca is toxic to cats and dogs if ingested, as it contains saponins that can cause irritation.
Children: Keep children away from the sharp, sword-like leaf tips which can easily pierce skin.
Contact allergens: The sharp, pointed leaf tips can cause puncture wounds and the sap may cause skin irritation.
Airborne allergens: The pollen can cause mild allergic reactions in sensitive individuals during the bloom season.
Edibility: The roots and leaves contain saponins that can cause severe stomach upset if ingested.

Growing it

Propagation: division, seed, cuttings
When to plant: Spring, Autumn
Overwintering: Ensure the soil is very dry before winter sets in. If in a pot, move to a sheltered, frost free area if you live in a very cold climate.
In containers: They grow well in large, heavy pots with excellent drainage, at least 40 cm wide.

Division

1. Dig up the parent plant in spring.
2. Separate the offsets or pups from the base.
3. Allow the cut ends to callous for two days.
4. Plant in well draining soil.

Pair with other drought tolerant plants that do not require frequent irrigation to avoid root rot.
