Ranchmama, Globe thistles are entirely different from what you're dealing with. I struggle with both Canadian and Bull thistle in my pastures, but globe thistles are, shall I say, exuberant but not metastatic in their growth. We have a three-sided shed in which we store firewood; access is needed most during winter when the globe thistles are died back. But my husband is complaining that it's hard to put wood into the shed now, and I have to agree that the globe thistle stands in the way like Rottweilers. They would make great plants for the back of a planting; they'd be great with daylilies in front as someone mentioned. Diane Please respond to SojournerSheep@bigfoot.com or droeder@javanet.com
