Snowdrops found growing in nature areas are wild forms of the cultivated plant. They are not native to the Netherlands. Cultivating new plants takes a couple of years, which is why it is done in the forest and not in nurseries. Such white snowdrop-covered woods can be seen in the Dennen on Texel. These bulbs are allowed to grow here, but they are no longer cultivated. In fact, it is not allowed to cultivate flowers in nature areas in this country. With the import of snowdrops from central France, the unusual species of land snails, Clausilias, was introduced to Texel. Other bulbous plants were also among the snowdrops, such as grape hyacinths.
