They are used as isolated specimens, in rockery, in bushy groups and in pots for balconies and terraces. They are ideal for gardens by the sea because they resist salinity.
Glorious Yucca needs full sun exposure and a rather dry and arid climate. It can withstand some sporadic and low intensity frost.
They can grow in sandy and dry soils. Transplantation or planting is done in spring.
Water very moderately, taking into account that they are very resistant to drought (1 watering per week at most).
They do not need fertilizers.
Prune the dry leaves.
They are very resistant plants to the usual pests and diseases.
They propagate from seeds sown in the nursery. Transplant 2 years after germination.
