In [[Dalsland]], Sweden, willow is normally blooming during the latter part of April. Maple appears during the first week of May. It’s important, but gives nothing to harvest. The most important month for honey in [[Dalsland]] is August.
The spring honey is usually used by the bee colony itself to grow up in preparation for the main nectar flow. Since the Nordic brown bees’ colony development starts slow, however, it does not support spring honey production. Despite this, it is sometimes possible to collect unifloral types of honey from the spring blooming season. The first main nectar flow usually comes from raspberry (Rubus idaeus).
