Black Willow

Salix Nigra

The willow tree had a mystical reputation in cultures across the world and over the centuries. The term “knock on wood” came from the Celtic culture where it was believed the willow tree brought good luck that was released by tapping on the trunk of the tree. In addition, the sound created by the wind as it passes through the willow branches and leaves of the tree was said to be the elves whispering to each other.

It’s believed Native Americans considered the North American native willow tree to also be good luck especially against bad weather. The flexibility of the branches of the willow made it better able to endure heavy wind storms in contrast to the tendency of the other area trees to have branches break due to high winds. According to legend, Native Americans would tie the branches of the willow tree to their boats to protect them and provide for safe travels or to their home to protect their families as well.

The Black willow loves and needs access to good soil moisture. The natural habitat for this tree is along stream beds, rivers, and lowlands. However, because it needs lots of moisture, it is not really the best neighborhood tree unless there is a good amount of room for its root system and it can be planted well away from any underground pipelines. Its extensive root system is well known for getting into and then clogging underground pipes and septic systems and even pushing up sidewalks.1

The benefits of this tree are its fast growth and that it helps with soil retention and erosion control2. Also, pollinators, such as bees and butterflies, benefit from the black willow because it is one of the earliest sources of pollen and nectar released from its clusters of yellow flowers early in the spring3.
