Even if you hear it often or read it occasionally on the retail labels: The term yucca "palm tree" is wrong. Despite all the external similarities, the yucca is by no means a palm tree, but an asparagus plant from the agave family. The plants, also known as palm lilies, form a fairly extensive genus with around 50 different species and 24 subspecies - some of which are very popular as indoor or garden plants. Whether and how often the plants bloom depends on the species and the specific cultivation conditions.
Outdoors, yuccas form magnificent flowers
Room yucca flowers only very rarely
The giant palm lily (Yucca elephantipes), for example, which is very popular as a houseplant, flowers very rarely and in pure room culture it almost never blooms. In order for the very vigorous plant to form flowers, it should already be a few years old and have optimal growth conditions. This includes the plant on the balcony or terrace during the warm summer months, and it should also be exposed to a short period of cold (but no frost!) in winter.
Garden yucca shows flowers after ten years at the earliest
The garden yucca, on the other hand, usually a Yucca filamentosa or a Yucca gloriosa, blooms tirelessly every year as long as it feels comfortable in its location. The flowering shoots can grow up to three meters high and are covered with numerous flowers not unlike lilies of the valley. Such a blooming yucca palm is truly magnificent to look at. If your yucca does not bloom, this could be due to the wrong location - but also because the plant is simply too young. Yuccas usually do not flower until they are around 10 years old. Faded shoots should always be removed.

Caution: Much of what is offered on the Internet by various dealers and dealer platforms under the name "Yucca" is actually a Dracaena fragans. This is related to the yucca and looks quite similar to it.
