Flowering season 2026
Permission for commercial or professional photo shoots, with or without models, or film recordings must be requested via the box office. In the Hallerbos you must always stay on the paths, also when taking pictures and filming. The soil and vegetation are fragile and very sensitive to trampling.
The use of drones is not allowed in the forest.
Here and there, a wild daffodil can still be seen in bloom. Wood anemones are currently the most striking spring bloomer. Especially when the sun shines, their flowers are fully open, creating a snow-white carpet of flowers in the forest. The white petals concentrate the warmth of the sun’s rays toward the center of the flower to attract pollinators. On the plateaus bathed in sun all day, bluebells are already blooming. But for now, it is the long, narrow leaves of the bluebells that stand out. They pierce through the dry beech and oak leaves and, where no wood anemones grow, color the forest floor green. Because the trees and shrubs do not yet have leaves, now is the ideal time to enjoy the birds in the forest. Be sure to bring binoculars. And as long as it is quiet in the forest, with a bit of luck you might encounter a roe deer. At this moment, they are often still together in small groups. If they are not disturbed, you can observe them for minutes while they search for food.
The flowering of the wild daffodils is past its peak. That is more than ten days earlier than in previous years. The flowers are beginning to wilt or have been damaged by the rain. The wood anemones are becoming the most striking spring bloomer. In the morning or during rain, their white flowers hang down somewhat forlornly, but once the sun provides sufficient warmth, the petals snap open like solar panels and follow the sun. The center of the flower, with the stamens and pistils, then heats up, thus attracting pollinators. The fields of bluebells are still green; narrow hyacinth leaves appear every day and are growing visibly. Here and there, plants already have flower buds, and the first purple-blue flowers are starting to stand out. Lesser celandine is blooming along the paths. The flowers, just like the wood anemones, are waiting for sufficient sun to open. Low to the ground, they form little yellow stars. The forest edges with blackthorn are now in full bloom.
Two days of almost summery temperatures are making themselves felt in the forest, making for wonderful walking weather. The wild daffodils are now in full bloom and are the most striking spring bloomer at the moment. Small wood anemones are peeking out from beneath the beech leaves. In sunny spots, wood anemones are already in bloom. Lesser celandine is blooming along the light-filled edges of the paths. Bluebell leaves, with their pointed tips, continue to pierce through the dry beech leaves everywhere. The brown, dead carpet of winter leaves is turning green. Here and there, the first flower stems with their purple-blue flowers are already emerging. At the forest edges, the snow-white flowers of the blackthorn are striking. Those who come for an early morning walk can enjoy the birdsong and the drumming of the woodpeckers. The chaffinch, great tit, blue tit, chiffchaff, and nuthatch are striking songsters. If you listen carefully near conifers you will hear the fine, high-pitched song of the goldcrest and firecrest.
The last snowdrops are still blooming, and here and there, along the forest edges, flowering catkins and female flowers can be found on the hazel. But the flowers of the cherry dogwood are particularly striking at the forest edges. In sunny spots along the paths, the first yellow stars of celandine appear. The most striking spring bloomer in the forest right now is the wild daffodil. Every day, new blooming daffodils appear, forming small, striking clusters. The leaves of the bluebells pierce through the dead beech leaves. Last winter, ‘reeblocks’ were placed around the small clusters of trees planted. This was to prevent roe deer from eating the young trees. The wooden fences will simply rot away after a few years, once they have fulfilled their protective role.
