DocKalle Quercus palustris

8.2.2024: Quercus palustris (swamp oak)

Quercus palustris (swamp oak) is a deciduous tree. In rare cases, it can grow up to 35 meters high. It is relatively short-lived and “only” lives to around 200 years (maximum).

It is originally native to eastern North America. As the name suggests, it can easily withstand several weeks of flooding. Its wood is often used for railroad tracks. Outside North America, the wood is rarely processed industrially due to its limited availability and very low distribution in the forestry industry. In Europe it is sometimes found in parks.

Acacia cyanophylla (willow leaf acacia)

Acacia cyanophylla (willow leaf acacia) is found particularly in North Africa but also in Australia. The growth height is (usually) 2-6 meters.
It prefers deep, sandy soil in damp areas.
The willow leaf acacia lives symbiotically with nodule bacteria (Rhizobiaceae) and can thus bind nitrogen from the air. It can conquer new habitats very quickly, as the young plants grow extremely fast.
