Pineapple Weed

Matricaria discoidea

Pineapple Weed is an annual herb characterized by its distinctive pineapple-like aroma when crushed. It grows up to 30 cm tall, featuring finely divided, fern-like leaves. Unlike true chamomile, it lacks showy petals, instead producing conical, greenish-yellow flower heads. It thrives in disturbed areas like roadsides and gardens. While sometimes used medicinally and as a flavoring, it's primarily an outdoor plant and doesn't typically thrive indoors due to its high light requirements and weedy nature. People may grow it for its novelty and edible qualities.
