Hardy garden yuccas
The filamentous palm lily (Yucca filamentosa)
The popular filamentous palm lily (Yucca filamentosa), for example, is frost-resistant, its flower stalks with numerous bell-shaped flowers can grow up to two meters (and sometimes even more) and look extremely impressive every year during the flowering period between June and October. The yucca species, originally from North America, is frost-hardy down to minus 15 ° C and only needs light winter protection at even lower temperatures. Very young specimens first have to get used to the temperatures and should therefore initially overwinter under cold house conditions. When planting, make sure that you choose a light and, above all, sheltered location - the filamentous palm lily does not like rain or drafts.

The candle palm lily (Yucca gloriosa)
Yucca gloriosa, also known as the candle palm lily, is even less sensitive to frost than the yucca filamentosa: this species can even withstand temperatures of minus 20 ° C and only needs light frost protection from bark mulch and leaves for longer periods of cold. In contrast, as with all palm lilies, moisture is more problematic. Make sure that the soil is loose and well-drained and that the plant is protected from excessive moisture if it rains frequently.
When is winter protection necessary?
Both yucca species do not need winter protection in normal winters. You should only mulch the root area and above all wrap the filamentous palm lily with garden fleece or reed mats when the temperatures drop very low or it is very cold for a long time. Above all, make sure that the roots are not damaged. If the above-ground parts of the plant are frozen back, you can cut them off and the plant will sprout again - provided the roots have remained healthy.
Hibernate yuccas properly in the pot
Container plants are exposed to frosty temperatures to a much greater extent than planted specimens, after all, there is no soil layer to protect them from the cold. Therefore, you should also overwinter hardy palm lilies during the cold season, preferably under cold house conditions. This means that you place the plants in a cool and bright room, the temperature of which is ideally between five and ten degrees Celsius. Container plants should be moved to their winter quarters before the first frost. In mild winters or when you do not have the option to overwinter indoors, you can also use suitable materials to pack the plants. Above all, the pot with the roots should be protected from frost.
The popular indoor yucca (Yucca elephantipes) is not hardy, but can also be outdoors in the warm and dry summer months. However, slowly get the plant used to the new environment.
