The phenological year progresses rapidly, and summer is almost in reach. Early summer attracts with red poppy fields and the first fresh strawberries. On these long days we like to be out and about in nature. A good opportunity for some Flora Capture or Flora Incognita observations!

This shrub is used by the German Weather Service (DWD) as indicator for the beginning of early summer. It is very common throughout Germany, so you may well use its flowers and fruits for producing syrup or jam. Please take a Flora Incognita or Flora Capture observation if you see a flowering elder!

The robinia, also known as false acacia or locust, is an exotic looking tree from North America, which has spread widely throughout Germany in the last decades. The pinnate leaves and mostly thorny twigs resemble acacia trees, which accounts for the species’ scientific name. The white flowers are useful for bees because of their high nectar content, but our need for their flowers are phenological investigations. That is why we ask you to photograph a flowering Robinia!

Although dogwood is a shrub native to Germany, its invasive growth poses a threat for many nature conservation areas. Due to its strong growth and resistance, it can quickly grow over open areas and thus threaten the habitat of open land plants. On the other hand, fallow areas e.g. along motorways are protected from erosion by dogwood plantings and the flowers serve as bee pasture.
