Bull thistle (also known as spear thistle) is another invasive thistle that has spread across most of North America and is most frequently found in disturbed habitats. The benefit of this sharp and prickly, hard to eradicate weed is that it is a very good source of food and nectar for bees, butterflies, birds amd insects.
