Common names
  • Speckled Alder
  • Tag Alder

  • Posted by ILPARW (southeast Pennsylvania - Zone 6b) on Aug 28, 2018 3:27 PM concerning plant:
    Speckled Alder is most easily recognized by its whitish lenticels (spots) on its stems. Its leaves of 2 to 4.5 inches long have irregular serrated teeth on the margins. It is usually larger than its very similar sister species of the Smooth or Tag Alder (A. serrulata) that has leaf margins with fine, regular teeth. The Speckled Alder has a large native range over most of Canada, all New England, New York, northern Pennsylvania, a bit in West Virginia and northeast Ohio, north and west Michigan, northeast Illinois, all Wisconsin, and northeast Minnesota in swamps, bottomlands, and wet areas. It is fast growing of about 2.5 to 3 feet/year and is short-lived of about 30 to 40 years. It is not sold by conventional nurseries, but can be bought by some native plant nurseries. It is a fine shrub-tree to grow along bodies and courses of water and in swamps.
