With the arrival of spring, herbaceous perennials have popped up throughout the landscape! However, as you tour the garden in early spring you may notice that certain perennials are noticeably absent. Don’t worry. Several perennials are tardy every year. These perennials require several weeks of warm soils and air temperatures before they begin to grow in spring. Sometimes they do not emerge from the soil until June!
The ISU Plant & Insect Diagnostic Clinic provides mushroom identification as part of our diagnostic service. To identify mushrooms, we need a fresh physical sample accompanied by digital pictures. See full instructions on our Mushroom identification page.
We do not identify mushroom solely from digital photos. When it comes to identifying mushrooms, we need a physical specimen to look for specific characteristics. We used books, different microscopes, and reagents.
