About Oncosiphon pilulifer (L.fil.) Källersjö
Globe chamomile, with the scientific name Oncosiphon pilulifer (L.fil.) Källersjö, is a straggly, branching annual plant with a strong scent. It grows up to 2 feet (60 centimeters) tall. Its leaves are either bipinnate or tripinnate, and feature a fleshy midrib that widens toward the base. This species produces globular flowers arranged in paniculate flower heads. It has no ray florets, and its disc florets are yellow. Globe chamomile is native to South Africa and Lesotho. It is also found in the Australian states of Victoria and Western Australia. In North America, globe chamomile grows from seed between November and January, when it begins to flower and produce new seeds. When sufficient moisture is available, three generations of the plant can grow and mature by April. The plant spreads via wind-transported seeds, and takes root in sunny, disturbed soil in both natural and cultivated areas. Contact with the plant or inhalation of its pollen can cause skin irritation or allergic reactions. A single globe chamomile plant can produce up to 4000 flower balls, each of which is made up of hundreds of individual flowers.
