Overview

Pineapple weed (Matricaria discoidea) is a low annual in the aster family, closely related to true chamomile. Its common name comes from the pineapple-like aroma released when the flowers and foliage are crushed.

Unlike its daisy-like chamomile relatives, its flower heads lack white petals, appearing as rounded greenish-yellow cones. It is a tough little weed that thrives in compacted soil, paths and roadsides.

How to identify it

Identify pineapple weed by its rayless, cone-shaped yellow-green flower heads and pineapple scent.

  • Small, low-branching annual, usually 2-12 in tall
  • Finely divided, feathery, fern-like leaves
  • Cone-shaped flower heads of tiny greenish-yellow disc florets with no white petals
  • Pineapple-like fragrance when foliage or flowers are crushed
  • Often grows in compacted soil along paths, driveways and field edges

Care & growing

Pineapple weed is a weed but a benign and fragrant one.

  • Light: Full sun
  • Water: Very drought-tolerant; thrives in dry, compacted ground
  • Soil: Tolerates poor, compacted, disturbed soils where little else grows
  • Temperature: Cool to warm season annual
  • Propagation: By seed; readily colonizes bare, packed soil
  • Control: Easily pulled or hoed; rarely aggressive enough to require herbicides

Habitat & origin

Pineapple weed is native to northeastern Asia and northwestern North America and has spread across much of the temperate world.

It is especially common in compacted, disturbed soils: footpaths, driveways, roadsides, gateways, farmyards and field margins. Its tolerance of trampling and poor soil lets it grow where many plants cannot.
