Whorled Rosinweed, Silphium trifoliatum
Asteraceae or Sunflower Family
 |
Sunflowerlike plant, 3 to 5 feet tall.
Flowerheads with several yellow ray flowers, and several tubular orange disc flowers, rather untidy-looking. Buds almost spherical, shiny and sticky. Most leaves in whorls of 3 or 4. Blooms in midsummer.
Native. In wildwood prefers woodland borders; fairly common along Wildwood Drive and the bikeway. Many sunflower-like plants occur in Wildwood, but this one is easy to identify. Key characters are the untidy head, the sticky spherical buds, and the leaves in threes or fours. |
