Even if this plant is often called that: The yucca is - despite all external similarities - not a palm tree. For this reason, care instructions for the yucca (or palm lily, as it is botanically correct) do not apply to palm trees. Of course, this also applies to the location.
The yucca feels at home in a bright window
Light and airy is ideal
Yuccas prefer a light, airy and warm location - no matter which specific species it is. Light, semi-shady places are generally better tolerated than full sun. You can also acclimate the yucca - especially the forest-hardy types for the garden - to a location in full sun, but you should proceed cautiously. Brownish spots on the leaves are often an indication of burns. By the way, you can tell a lack of light on the yucca by the leaves drying up from below. This phenomenon often - but not always - occurs in connection with insufficient humidity.
Indoor yucca outdoors: the right place
During the warm summer months, the not frost-hardy indoor yucca also feels at home in a bright and sheltered spot in the garden or on the balcony or terrace. As with the garden yucca, the same applies here that the plant can be placed in full sun - but only after it has gotten used to it. However, the intense midday sun should be avoided in any case.
tips
The garden yucca (e.g. frost-hardy species such as the Yucca gloriosa or the Yucca filamentosa) should be as sunny as possible and in sandy, well-drained and dry soil. The otherwise easy-care and robust relative of the Yucca elephantipes (giant palm lily), which is often cultivated as a houseplant, does not tolerate excessive moisture at all.
