Asteraceae

Asteraceae is commonly known as the aster, daisy, composite, or sunflower family. Most Asteraceae species are herbaceous plants, but there are also shrubs, vines, and trees. They have a widespread distribution, occurring in various habitats from subpolar to tropical regions on every continent except Antarctica.

Asteraceae is a large and diverse family of flowering plants, commonly known as the aster, daisy, or sunflower family. It is one of the largest plant families, with over 32,000 currently accepted species in more than 1,900 genera.

  • Characterized: Asteraceae plants are characterized by their composite flower heads, which typically contain many small florets arranged in a dense cluster.
  • Flower Structure: Asteraceae flowers are typically composed of small individual flowers arranged in a dense head or cluster, often surrounded by overlapping bracts (phyllaries) that resemble petals.
  • Leaves: Leaves are usually alternate or opposite and can vary widely in shape and size depending on the species.
  • Inflorescence: The flowers are arranged in various types of inflorescences, including solitary heads (like sunflowers), corymbs, panicles, or spikes.
  • Fruit: Asteraceae fruits are often achenes, which are small, dry, one-seeded fruits that do not split open at maturity.
  • Distribution: Asteraceae plants are found worldwide, in a wide range of habitats from deserts to tropical rainforests, and from sea level to high mountains.
  • Diversity: Some well-known plants in this family include sunflowers, daisies, chrysanthemums, and lettuces.
  • Pollinator Attraction: Asteraceae flowers attract a wide range of pollinators, including bees, butterflies, and other insects.
  • Weed Species: Some Asteraceae species, like dandelions, are considered weeds in certain contexts but have ecological benefits.
