Comments: A spiny thistle of the sunflower family that is crowned by bright purple thistle flowerheads from April through July. Relatives have invaded thousands of acres of lands in the far west and is very difficult to eradicate. Maintenance level is high to keep it under control. Makes an exceptional specimen as a stand-alone single and in mass plantings. Provide full sunlight and a well drained soil. Does quite well in raised planters.
