Pineappleweed

Matricaria discoidea, commonly known as pineappleweed or wild chamomile, is a small, aromatic flowering plant in the Asteraceae family. Native to North America, Europe, and Asia, pineappleweed is often found in disturbed areas, along roadsides, and in waste places. Here's an informative description of Matricaria discoidea:

Appearance:

1. Habit:

   • Pineappleweed is an annual plant that typically grows low to the ground, reaching heights of about 10 to 30 centimeters (4 to 12 inches).

2. Leaves:

   • The leaves are finely divided, feathery, and alternate along the stems.
   • The foliage has a distinct, pungent aroma when crushed.

3. Flowers:

   • The flowers are cone-shaped and resemble tiny, greenish-yellow, button-like structures.
   • The flower heads lack the typical white petals found in other chamomile species.

4. Odor:

   • When the leaves or flowers are crushed, they emit a sweet, fruity, pineapple-like fragrance, hence the common name "pineappleweed."

Identification:

1. Distinctive Aroma:

   • The pineapple-like aroma distinguishes Matricaria discoidea from other plants, especially when leaves or flowers are crushed.

2. Button-Like Flowers:

   • The cone-shaped, button-like flower heads without prominent white petals are a key identifying feature.

3. Feathery Leaves:

   • The finely divided, feathery leaves are another characteristic trait.

Habitat and Distribution:

1. Habitat:

   • Pineappleweed thrives in disturbed areas, gravelly soils, roadsides, and waste places.
   • It can be commonly found in areas with human activity.

2. Distribution:

   • It is distributed widely, occurring in North America, Europe, and Asia.
