Announcing the release of our new Native Thistle Guide! Native thistles are a largely misunderstood and wrongly maligned group of wildflowers. Often confused for their prickly non-native counterparts, native thistles are valuable resources and fill important ecological niches alongside more showy wildflowers.
In our new practitioner's guide you’ll find one of the most comprehensive discussions of the value of native thistles for pollinators and other wildlife, as well as a detailed account of the conservation status of native thistles, a brief history of invasion by Canada thistle, and a practical section on the production of native thistle seed for use in restoration projects.
