At senescence, which often occurs when the plant reaches a diameter of approximately 0.5 metres (1.6 ft), the plant produces a tall stalk of maroon ray flowers which resemble the sunflower in just a few weeks. Flowering usually occurs from July through October. This flowering stalk may have up to 600 heads of up to 40 outlying ray flowers and 600 disk flowers and is pollinated by flying insects like Hylaeus (Nesoprosopis) volcanicus. The flower stalk may reach up to 2 metres (6.6 ft) in height and has numerous tiny sticky hairs to prevent crawling insects from damaging the plant.
