I thought this was a Cottonwood Tree but my research has this as a Sandbar Willow Shrub. Well, actually it is a thicket of said shrubs.
Here I thought that willows only came in tree form but I learned that they also grow as a shrub. This group of sandbar willow shrubs are native to North America and grows 6-15 feet tall. Since all willows love moisture, it is common to see them growing alongside streams. Their interlacing roots help to hold back soil and stops erosion. I found this group alongside of a small stream last May.
In the spring, catkins appear on the branches, and in May-June the catkins open to release the cottony seeds.
I mentioned that willows love moisture, so naturally their roots will gravitate towards moisture. You would be smart not to plant willows near water pipes or sewer lines.
Thanks for stopping by.
