Interesting facts about the holly
Ilex, also known colloquially as holly, is found in many species worldwide.

Winter magic in a bouquet: festive accents with holly (Ilex)
Holly (Ilex) is a special addition to winter bouquets and floral arrangements. With its glossy, deep green leaves and bright red berries, it creates striking accents that spread a festive atmosphere and at the same time convey a feeling of naturalness and elegance. Ilex is a decorative element not only in bouquets but also in wreaths or arrangements, as the branches have a long shelf life and dry well. Whether as individual branches or in combination with other seasonal plants, holly brings colour, texture and winter magic to any floral arrangement.
