Pineapple weed (Matricaria discoidea) is a common introduced small herb found in compacted soils of disturbed areas, such as the borders of dirt trails. The whole plant is edible raw. The foliage is bitter but the flowers are sweet. The flower looks and smells like chamomile (they’re related), and have similar properties (calming, soporific, pleasant tasting) as chamomile when brewed into tea.
